摘要

摘要通过求解完整的纳维-斯托克斯方程，并使用 Falkner-Skan-Cooke 轮廓的自相似单参数族和 Gaster 提出的双参数族的边界层轮廓，对围绕后掠翼和旋转体的流动计算的边界层纵向和横向速度分量轮廓进行了近似比较。结果表明，在三维分离附近使用双参数系列剖面对数值剖面进行近似具有明显优势。

USING TWO-PARAMETER VELOCITY PROFILES FOR THREE-DIMENSIONAL BOUNDARY LAYERS

Approximations of the profiles of the longitudinal and transverse velocity components in the boundary layer calculated for the flows around a swept wing and a body of revolution by means of solving the full Navier–Stokes equations and using the boundary layer profiles from the self-similar one-parameter family of the Falkner–Skan–Cooke profiles and two-parameter family of profiles proposed by Gaster are compared. A significant advantage of using the approximation of the numerical profiles near three-dimensional separation by profiles from the two-parameter family is demonstrated.
