Análise e modelagem de métodos numéricos para a solução de problemas inversos em transferência de calor em regime transiente bidimensional em soldagem

Abstract

The welding process involves large heat flows and high temperature gradients, whose study and forecasting may cause several defects during the process to be avoided, but it is very difficult to experimentally measure the heat flux imposed on the weld joint due to the movement of the process and often the addition of reinforcing materials. In this type of problem it is necessary to use inverse techniques of heat transfer, initially a thermal model of the real problem is generated, it is mathematically modeled, and applying numerical methods is the solution of the direct problem involved for the solution of the inverse problem the technique chosen was the method of the Golden Section. After computationally implementing both the direct and inverse problems, we analyzed the results obtained with the algorithms.
