Abstract

Abstract

This paper introduces an optimization method based on the CFD（Computational Fluid Dynamics） technology.The method combined the CFD code with the 3D CAD code and the CAO（Computational Aided Optimization） code,and performed the structural design of the mixing vanes to improve the thermal-hydraulic performance of grids,and verified the results of the optimization through the CFD analysis on 5×5 grid.The results show that it is feasible to adopt the optimization technology to optimize the design of the spacer grid.
