不同雷诺数对钝前缘三角翼气动特性影响的研究

通过求解三元非定常N—S方程的方法，对钝前缘三角翼的流动进行了数值模拟，研究了亚声速条件下不同雷诺数对钝前缘三角翼分离涡的影响。计算结果与试验结果进行了详细的比较，两者都证明雷诺数的增大对钝前缘分离涡的分离有明显的延迟作用。

Different Reynolds Number Effects on a Blunt-leading-edge Delta Wing

The subsonic leading - edge vortex separation flow over a blunt - leading - edge delta wing at different Reynolds numbers have been studied, by solving the three dimensional unsteady Navier - Stocks equations. The computed results are compared and in good agreement with the test results. The results both show that increasing Reynolds number can delay the leading edge vortex separation evidently.
