Level Set Method for Topological Optimization of the Naiver-Stokes Fluid Flow

摘要：

　　This paper presents a general algorithm for topological optimization of the incompressible Navier-Stokes fluid flow based on a level set method.This is a direct extension of our previous work on Stokes flow of such problems.First we obtain the shape sensitivity analysis using the material derivative concept and adjoint variable technique,and then we couple the shape sensitivity analysis result into the level set function as the advection velocity.Since the level set method is implemented in an Euleran framework,the computational cost of the proposed algorithm is moderate.A Benchmark example is provided to illustrate the efficiency and validity of this method.
