  • Volume 10 Issue 1 - Latest techniques and practical notes on anti-surge
           systems for centrifugal compressors
    • Abstract: Almasi, A
      The operating range of process centrifugal compressors is limited by an instability range commonly called "surge", which occurs during low flow or high head conditions and can result in extensive damage. There are high expectations to improve anti-surge systems of process compressors to increase reliability as well as energy efficiencies and performance. Practical recommendations on anti-surge system sizing, selection, configuration and design are presented. Considerations regarding stall, choke, dynamic studies, anti-surge loop configuration, recycle cooling, anti-surge valve, instruments and anti-surge system parameters are also discussed. Case studies are presented.

    • Abstract: Almasi, A
      Practical recommendations on modern compressor casing, impellers, shaft, internals, material selection, control system, surge prevention systems, diaphragms, casing connections, nozzle loads, bearing, and balance piston are explained. This article highlights the lessons learned from several industrial experiences in relation to the selection, design and manufacturing of compressor components especially critical parts such as dry gas seals, seal support systems, control units and surge prevention systems for the centrifugal compressors. Particularly the tandem type seal is discussed in detail. Case studies are presented.

  • Volume 10 Issue 1 - Process analysis of abrasive jet micromachining for
           brittle materials
    • Abstract: Li, HZ
      Abrasive jet micromachining (AJM) is a non-traditional machining process based on the erosion of substrates by an abrasive-laden air jet. It is a promising machining technique for the cost effective fabrication of micro-devices from brittle and hard materials. For the machining process to be more efficient and better predictable, mathematical models for the AJM process are necessary. This paper presented an analysis of the AJM process for brittle materials. The analysis is based on a fundamental erosion model of solid particle impact for brittle materials, and a recently developed model for the particle velocity in micro-abrasive jet, to form a mathematical basis for AJM process modelling and optimisation. Experimental study on the flow characteristics and the effects of some important process parameters are also given.

  • Volume 10 Issue 1 - Effect of cross-sectional geometry on superelasticity
           of helical nanobelts
    • Abstract: Li, N; Cui, Y; Fu, D
      The shape memory effect (SME) and the superelasticity make nanoscale chiral structures such as helical ZnO nanobelts promising for a wide range of important applications. In this paper, based on the non-linear rod model with surface effect (Wang et al, 2011), the effects of surfaces and geometrical size of the cross-section on the superelasticity of the helical nanobelts have been investigated quantitatively. Our results demonstrate the superelasticity of helical nanobelts exhibit a distinct size effect, depending on the cross-sectional geometry. We also show the efficiency of the energy storage and retrieval of the helical nanobelts induced by the superelasticity depends strongly on the cross-sectional geometry.

  • Volume 10 Issue 1 - Improving accuracy of opening-mode stress intensity
           factor in two-dimensional media using fundamental solution based finite
           element model
    • Abstract: Wang, H; Qin, Q-H; Yao, W
      A hybrid finite element method (FEM) is developed for determining stress intensity factor of opening-mode cracks. The model is based on fundamental solutions and higherorder displacement extrapolation. In the present formulation, linear combination of fundamental solutions and shape functions are respectively used to approximate the element interior and frame fields. The equality of the two approximations is enforced through a hybrid functional and element boundary integrals are involved only. Numerical examples are considered to investigate effects of element size, number of elements and crack length on crack tip singularity. Results show that the proposed approach can achieve better numerical accuracy than conventional FEM.

  • Volume 10 Issue 1 - Combustion chamber geometry effects in spark ignition
           engine exhaust emissions
    • Abstract: Zefaan, H
      The paper presents experimental results showing the effect of hemispherical, cylindrical and oval bowls-in-piston on exhaust gases within the cylinder of spark ignition engines. Results indicate that bowls increase both heat transfer and flame speed. Consequently, flame ability must become wide to reduce both engine emissions and cycle combustion variability. Hemispherical effect ranked first on hydrocarbon and carbon monoxide emissions, followed by cylindrical then oval. Nitrogen oxides are in opposite direction, with oval ranked first, followed by cylindrical then hemispherical.

  • Volume 10 Issue 1 - Mathematical approach for optimal machining fixture
           layout and clamping forces
    • Abstract: Selvakumar, S; Arulshri, KP; Padmanaban, KP; Sasikumar, KSK
      Machining fixtures are used to locate and constrain a workpiece during machining operation. An ideal fixture design exhibits minimal moment while machining. The purpose of this work is to design an optimum fixture layout in order to reduce the maximum elastic deformation of the workpiece by reducing the moment caused by the clamping and machining forces acting on the workpiece while machining. This can be achieved by selecting the optimal locations of fixturing elements such as locators and clamps. The objective equations are formed based on equilibrium conditions and are solved for minimum value of clamping force condition for various fixture layouts. The required equations are formulated based on the equilibrium conditions of forces, moments and stick/slip conditions. Then these equations are solved for several fixture layouts and the corresponding clamping force sets are found. Thus the clamping forces satisfying constraints, along with its respective layout are solved for deformation values using ANSYS software. Layout providing minimum deformation value is selected as the optimal one.

  • Volume 10 Issue 1 - Experimental investigation on the effect of applied
           pressure on microstructure and mechanical properties of squeeze cast AC2A
           aluminium alloy
    • Abstract: Senthil, P; Amirthagadeswaran, KS
      This investigation focuses on the attempt made to prepare AC2A castings of a non-symmetrical component through squeeze casting process. Samples were produced to study the effect of squeeze pressures (0.1, 25, 50, 75, 100 and 125 MPa) on microstructure and mechanical properties of the alloy. Results of hardness and tensile tests indicated that squeeze cast specimens exhibited higher mechanical properties than gravity die cast specimens. This was mainly due to applied pressure which resulted in effective filling of the melt into die cavity, microstructural refinement and good heat transfer between the melt and the die. Pressure of 50 MPa was found to be sufficient for pore free castings and pressure of 100 MPa was noted for sound castings. From this study, the squeeze casting process is noted to be suitable for processing this alloy.

  • Volume 10 Issue 1 - Anomalous sub-diffusion equations by the meshless
           collocation method
    • Abstract: Gu, YT; Zhuang, P
      Recently, many new applications in engineering and science are governed by a series of fractional ordinary differential equations or fractional partial differential equations (FPDEs), in which the differential order is with a fractional order. The anomalous sub-diffusion equation (ASDE) is a typical FPDE. The current dominant numerical method for modelling ASDE is finite difference method, which is based on a pre-defined grid leading to inherited issues or shortcomings. Because of its distinguished advantages, the meshless method has good potential in simulation of ASDE. This paper aims to develop an implicit meshless collocation technique based on the moving least squares (MLS) approximation for numerical simulation of ASDE. The discrete system of equations is obtained by using the MLS meshless shape functions and the meshless collocation formulation. The stability and convergence of this meshless approach related to the time discretisation are investigated theoretically and numerically. The numerical examples with regular and irregular nodal distributions are used to validate and investigate accuracy and efficiency of the newly developed meshless formulation. It is concluded that the present meshless formulation is very effective for the modelling and simulation of ASDEs.

  • Volume 9 Issue 2 - Construction of the marginal abatement cost curve:
           Retrofitting carbon capture and storage in Australia
    • Abstract: West, J
      Marginal abatement cost curves are a principal tool used for measuring the relative economic impact of emissions abatement mechanisms. Abatement curves can be constructed using either a top-down approach based on aggregated microeconomic models or using a bottom-up approach based on an engineering assessment that analyses different technical potentials for emission reductions. While top-down models offer simplicity and ease of interpretation, they are not as robust as the bottom-up approach, particularly for assessing the implications of new technologies such as carbon capture and storage (CCS). Using a bottom-up approach and incorporating real options analysis, this study redefines the relative abatement costs for retrofitting post-combustion CCS technology to coal-fired generators and then reconstructs the Australian marginal emissions abatement curve. The revised curve provides power generators and other industry sectors with more accurate and stable abatement cost estimates for these technologies relative to alternate abatement options.

  • Volume 9 Issue 2 - A simple CAD method for constructing sand-heap
           formations as an analogous means of determining the fully plastic torque
           capacity of various structural sections
    • Abstract: Bardell, NS; Evans, GJ
      A brief review is presented of the sand-heap analogy as a means of determining the ultimate plastic torque capacity of a ductile metallic prismatic bar of known cross-section. A novel method using an industry-standard computer-aided design (CAD) tool is then described for determining the shape and corresponding sand-heap volume for a general cross-section that can include the presence of keyways, fillets, rebates, and holes. Existing solutions for simple regular cross-section shapes are used as a benchmark for the solutions from the new method, and perfect agreement is found. Subsequent examples are presented which demonstrate the ease with which sand-heap formations and their corresponding volumes can be found for more general cross-sections that are more representative of those used in practical engineering applications.

  • Volume 9 Issue 2 - Simulation of viscous and viscoelastic flows using a
           RBF-galerkin approach
    • Abstract: Ho-Minh, D; Mai-Duy, N; Tran-Cong, T
      In this paper, two-dimensional flows of viscous and viscoelastic fluids are simulated using radial-basis-function networks (RBFNs) and Cartesian grids. To solve the governing equations, high-order approximations based on one-dimensional integrated-RBFNs are employed to approximate the field variables and the Galerkin discretisation formulation is utilised to transform the differential equation into a set of algebraic equations. The main distinguishing feature of the above combination is that two processes, namely the representation of the field variables and the discretisation of the governing equations, are both based on integration. In sharp contrast to conventional Galerkin methods, derivative boundary conditions are presently imposed in an exact manner. Two test problems, namely natural convection of a Newtonian fluid in a concentric annulus and fully-developed flow of an Criminale-Ericksen-Filbey (CEF) fluid in a rectangular duct, are studied. Results obtained are compared with published data in the literature.

  • Volume 9 Issue 2 - Characteristics of interlaminar stresses for damages in
           adhesively-bonded composite single lap joints
    • Abstract: Panigrahi, SK; Zhang, YX
      In this paper three-dimensional non-linear finite element analyses are carried out to evaluate accurately the stresses over the different critical surfaces for adhesion failure, cohesion failure and delamination damages of an adhesively-bonded fibre-reinforced polymer (FRP) composite single lap joint (SLJ) subjected to an in-plane loading. The top and bottom adherends of the SLJ are formed by eight layers of unidirectional graphite FRP composite and the material of the adhesive is epoxy. The out-of-plane stresses and their distribution over the critical surfaces are presented, and conclusions about the damages and failures for the adhesively-bonded composite SLJ are drawn.

  • Volume 9 Issue 2 - Advanced methods for shop performance tests of process
           centrifugal compressors
    • Abstract: Almasi, A
      Centrifugal compressor purchasers and end-users realise the value and payback of accurate and proper shop performance test and shop mechanical run test. Shop test is a necessary step for centrifugal compressor future reliability and trouble free operation. Procedures and methods to correctly implement shop performance test and shop mechanical run test of process centrifugal performance are discussed. ASME-PTC-10 type 1 performance test should be done wherever possible. Otherwise arrangement and details of ASME-PTC-10 type 2 performance test, as close to specified operating condition as possible, should be fixed before machine order.

           arrangements of LNG plants
    • Abstract: Almasi, Amin
      This article presents practical notes and guidelines on driver type, power management and compressor train arrangement for LNG plants. Electrical motor driven refrigeration trains are used successfully in small and medium size LNG facilities and many operators are investigating to use this technology for large LNG modules. Optimum compressor and driver arrangement for LNG plants are discussed. Evaluations show overall installation and operation costs of the gas turbine driven refrigeration system and electrical motor driven trains is close to each other. Case studies are presented.
