Abstract
Life cycle time expansion of equipments and devices such as internal combustion engines become big issues under heat loads. Topology optimization for heat diffusion is one of expected solution to overcome this problem. This paper has tried to establish a topology design optimization method of coupled state filed by COMSOL Multiphysics. As a first step to this purpose, we have solved topology optimization problems of heat diffusion by SIMP method. Several numerical design examples are implemented in order to confirm the validity of optimum design of heat diffusion.
