Regarding the drag reduction of ridge-like surface as optimization goal, this paper has optimized V-like and U-like surface using genetic algorithm in the context of given sizes and obtained the ridge-like structure size with the best drag reduction effect. Comparative analysis of the surface resistance and turbulence characteristics and the velocity distribution near the wall show that the optimized ridge-like surface has good drag reduction effect and the drag reduction of V-like surface is better. The drag reduction of optimized ridge-like surface has increased significantly and this shows that the method optimizing ridge-like structure using genetic algorithm is feasible. The optimization method can be used for navigation devices and other fluid mechanical shape optimization design.
