Análise numérica de problemas térmicos tridimensionais baseada em método implícito de avanço no tempo com aplicação em dissipadores de calor passivos

Abstract

This work consists on the expansion of an existing code able to simulate bidimentional transient problems of heat transfer using the numerical finite difference method, developed by CONCI e GOMES (2017), so that it can be capable of solving tridimentional problems with more complex geometries, along with the development of a code that preconditionate meshs for the same. For the analisys it is used the iterative method GMRES with the préconditioner MILU0. The code is implementated, verified and validated, reaching the sixth order of precision, and, then, aplied in geometries of heatsinks to attest its efficiency, making possible its utilization in future analisys of heatsink geometries.
