摘要
In order to analyze Reynolds number effects on aerodynamic characteristics of grid fins, numerical simulation was conducted in supersonic speed based on a typical grid-fin configuration. The numerical results indicate that Reynolds numbers have little influence on the lift slope, but have significant influence on drag characteristics. Further researches show that Reynolds number effects mainly exist on frictional drag. Based on the numerical results, a correction method of Reynolds number effects on drag coefficient was proposed in this paper.
