Desarrollo de software académico para simulación de fenómenos de transporte mediante métodos numéricos.

Abstract

In the pyrometallurgical industry, the processes are carried out at high temperatures. Therefore, it is important to characterize the heat transfer phenomena, to reduce heat losses and costs in production lines. In addition, to guarantee the industrial safety of the process. process. Mathematical modeling and simulation allow to understand the phenomena of heat transfer and predict the behavior of the system under established conditions. The aim of this academic paper was to develop a software for the simulation of heat transfer by conduction in simple 2D geometries using finites differences method. First, simple discretized 2D geometries were defined in control elements for numerical simulation of heat transfer. Once the geometries were defined, the model and the graphical user interface were applied with similar conditions of a pyrometallurgical furnace. Characteristic temperature profiles of conduction heat transfer phenomena were obtained for the conditions and materials examined. In addition, the results determined by the software were validated by comparing them with results calculated by analytical methods, obtaining error percentages of less than 0.2%. Finally, a graphical interface was developed to make the model accessible as free software for engineering students and teachers.
