Resolução de problemas de transferência de calor e suas aplicações

Abstract

The study of transport phenomena characterizes an area with various applications in different fields of science and engineering. In the case, in heat transfer phenomenon innumerous applications that can be found, such as the heat transfer in reactors, distillation columns, dryers, among others. The physical analysis of these problems, whose mathematical formulation depends on hypotheses considered, requires the resolution of models with different levels of complexity (algebraic equations system, differential equations system, integro-differential system and differential algebraic system), and which difficultly present analytical solution. In academic context, the treatment of these problems in different disciplines of engineering undergraduate courses is not a trivial task, given the structure available by universities and due to inherent difficulty in working with numerical methods. In this contribution, the aim is development of a graphical environment for the treatment of heat transfer problems in disciplines of Transport Phenomena. For this purpose, it is considered the Scilab® software, a programming environment that presents source code with free access, as platform for the development of computational routines. From the results obtained by using the GUI (Graphical User Interface), it is possible to conclude that the development of this type of platform will help the professors of Transport Phenomena in relation to physical analysis both of the problems of heat transfer in solids and of the charts of Gurney Lurie without the concern with the development of specific computational routines.
