Abstract

Structured surfaces play an essential role in reducing surface drag. In order to obtain the drag reduction performance of structured topological fish scale surface, the computational fluid dynamics theory was used to analyze and study. First, the parameters of the fish scale surface are designed by topology. The fluid model of the surface is established, and the CFD software ANSYS Fluent numerically analyzes the surface. The variation regularity of the surface's friction coefficient in different areas is studied, and the drag coefficient of the surface is analyzed. The research shows that the variation and fluctuation of the surface's friction coefficient are different in different areas. The drag reduction ability of the structured topology fish scale surface is better than that of the fish scale surface, and the best drag reduction effect of the structured topology fish scale surface is about 5.36%.
