| 摘 要： | 本文提出一种适用于可控环量机翼研究的势流/粘性流的数值解法,包括钝体分离绕流的一种势流解,以及改进的Spalding统一边界层理论的解。通过对具有壁面切向喷流可控环量圆柱绕流和类椭圆翼绕流所作出的数值计算表明,在其计算模型确定后,就不必依赖实验数据来模拟实际问题,计算结果与实验数据符合较好。

| Abstract: | This paper presents the Viscous/Inviscid interaction techniques for calculating the flow on the circulation controlled airfoil with tangential jet blowing from surface slots. The calculation models are given to solve potential velocity distribution on the sail airfoil of large attack angle and quasi-elliptic airfoil in two-dimensional separated flows. The viscous problem is calculated by modified Spalding's unified boundary layer theory. Several representative sample cases are calculated and many aerodynamic characteristics are obtained . The solutions gotten generally agree with available computation and experimental results. |
