Análise Qualitativa da Condução Transiente em uma Peça de Alumínio Através do Método das Linhas

Abstract

This work aims at the qualitative analysis of the cooling of a cast aluminum part with a specific geometry in order to understand the process and the reasons for the appearance of a defect in the samples of the experiment that inspired this study. This study was based on the fundamentals of heat transfer for transient heat conduction and was used numerical and mathematical methods to create a preliminary model for analysis of the phenomenon. With the model constructed, a simple mesh was created and through the finite difference method equations were elaborated for each node of the mesh. Using the method of the lines, an approximation of the problem that before was composed by a system of partial differential equations for a system of ordinary differential equations was done, which allowed that a computational solution already present in the used software was used, which in the case was the SCILAB. After the development of the algorithm it was necessary to organize the data obtained in a temperature matrix that allowed a better visualization and analysis of the results
