  • Simulation of biomass pneumatic drying with ascending swirling

    • Abstract: Considerando la forma de capa que adquieren las partículas durante el proceso estudiado fue necesario definir la relación existente entre el área de transferencia de calor y masa y el flujo de material para poder simular con mayor precisión este tipo de secado. Los resultados de la simulación se compararon, a través de un análisis estadístico basado en el programa Statgraphics-Centurion V15, con los resultados obtenidos en otros estudios de secadores neumáticos de bagazo y fueron semejantes por lo que se concluyó que es correcta la definición hecha sobre la relación área/flujo de material definida en este trabajo y que es posible reducir la altura de los secadores neumáticos de biomasa usando este método. Esta reducción que se puede apreciar a través del índice de Reducción de Altura (IRA) de la columna de secado, definido en el trabajo, permitirá secadores de biomasa más compactos.Considering the layer form acquired by the particles during the studying process it was necessary to define the relation cheap between the heat and mass transfer area and particles flow to simulate with more precision this kind of drying. The simulations results were compared, by a statistical analysis based in Statgraphics-Centurion V15 program, with the results obtained in others pneumatic bagasse dryers studies and were similar and for that reason it was categorical that is correct the definition made about the relation cheap area/material flow defined in this work and it’s possible to reduce pneumatic dryer height by using this method. This reduction that can be seen by the Height Reduction Sing (HRS) of the drying column, defined in the work, will permit more compact dryers.

           slip-form machine

    • Abstract: The goal of this paper is to expose the parametric design process of an immersed vibrator, belonging to a horizontal slip-form machine used to prefabricate ferrocement panels. A mathematical model was constructed and validated, which interrelates variables of geometric configuration, mass distribution, excitercharacteristics, stresses and accelerations in remarkable points, Eigenfrequencies, technological operations, energy, costs and other aspects. Based in this model, it was solved the design problem by a method employing dichromatic graphs. For the optimized solution it was iteratively executed a simulation algorithm. To facilitate programming, the simulation algorithm was organized in a particularly advantageous manner for complex systems. As a final result, an optimized design solution was obtained and subjected to physical tests, which demonstrated overcomes previous versions of the vibrating device, so the applied method is appropriated for parametric design of similar devices, when general configuration, functioning principles, forms, and other fundamental aspects, are previously defined.El objetivo de este artículo es explicar el procedimiento de diseño paramétrico del vibrador de inmersión deun molde deslizante horizontal empleado para prefabricar paneles de ferrocemento. Para ello se construyó y validó un modelo matemático integral que interrelaciona variables de la geometría, la distribución de masas, las características del vibro-excitador, los esfuerzos y aceleraciones en puntos importantes, las autofrecuencias de oscilación, la tecnología, los costos y otros aspectos. Sobre este modelo se resolvió un problema de diseño, utilizando un método que emplea grafos bipartitos. Para facilitar la programación el algoritmo fue organizado en una forma particularmente ventajosa para sistemas complejos. Como resultado principal se obtuvo un prototipo con diseño óptimo, el cual fue construido y sometido a pruebas físicas. Se demostró que el nuevo diseño tiene mejores prestaciones que los anteriores, por lo que el método aplicado se considera apropiado cuando la configuración general está previamente definida.
