Optimum Design for Microstructures of Closed-Cell Materials Based on Thermal Conductivity

Taking our proposition about the grid-based simulation for the microstructure of the closed-cell foam into account, and choosing position of voids as optimal variables, this paper builds an optimal model for the two-phase material with maximizing the effective thermal conductivity of the microstructure. Then the paper seeks its solution by using the genetic algorithm. The numerical results show that the optimal model we built is reasonable and the optimal algorithm we used to solve this model is also effective. Furthermore, the results illustrate how the related factors make an effect on the optimal solution.
