Method to optimize the strake structure was found based on the analysis of mitigating the vortices around the strakes.It's calculated that transverse force coefficients of strakes in fluid with different Reynolds numbers,it's got the effects of Re's numbers to the vortices around the strakes.水利论文{7H,UQ I8zf%g
