Outline of Final Research Achievements

This research presents a topology optimization method that deal with two-phase fluid for the design of fluid devices. In the proposed method, the Lattice Boltzmann method (LBM) is employed to compute the multiphase flow field and the adjoint field during the topology optimization process. The topology optimization algorithm is constructed based on the level set method and the Finite Element Method (FEM). Additionally, several numerical examples are provided to demonstrate the effectiveness of the proposed topology optimization method.
