Resumen
El presente trabajo recopila la informaci´on, experiencias y conclusiones que permiten formar la base t´ecnica y te´orica para la optimizaci´on de la geometr´ıa de un secador de plantas arom´aticas dividido por bandejas. La optimizaci´on fue realizada con base en un modelo matem´atico del secador y las mediciones experimentales obtenidas en un secador industrial. Se plante´o el sistema de ecuaciones diferenciales necesarias para modelar el fen´omeno de secado en el equipo, estas ecuaciones fueron resueltas usando el software libre OpenFOAM R y los resultados fueron validados con las medidas experimentales realizadas en el secador. Un modelo simplificado del flujo del aire a trav´es del secador, fue usado para la optimizaci´on de la geometr´ıa. El algoritmo de optimizaci´on fue ejecutado con el software libre DAKOTA Project. Finalizando se presenta la geometr´ıa optimizada.
Abstract. This thesis collects the information, experience and conclusions that constitute the technical and theoretical basis for optimizing the geometry of an aromatic plants dryer divided by trays. The optimization was carried out based on a mathematical model of the dryer, and experimental measurements. A set of differential equations that allows the simulation of drying phenomena in the dryer were established. These equations were solved using the free software OpenFOAM R and validated with experimental measurements in the dryer. For the geometric optimization a simplified model was develop. The optimization algorithm was solved using the DAKOTA Project software. The optimized geometry obtained from the proposals is shown.
