BESO Method for Solving Topology Optimization Problems in Fluid Mechanics
The Bi-directional Evolutionary Structural Optimization(BESO)algorithm is applied to solve the topology optimization problem in fluid dynamics.The Navier-Stokes equation is used as the governing equation,and the purpose of topology optimization is to find the optimal path of fluid flow and minimize the total dissipation under the constraint of a given fluid volume.The artificial permeability term is added to the Navier-Stokes equation to apply the no-slip boundary condition;The sensitivity analysis results are obtained by adjoint method and combined with BESO method.Finally,the stability and effectiveness of the proposed method in dealing with fluid dynamics topology optimization are validate by benchmarking examples.
