【摘要】 本文在相对正交曲线座标系中建立了两类相对流面（S₁流面和S₂流面）上边界层微分方程组。所给方程不仅描述了静、动叶流道内边界层流动的一般特性,而且可用于叶片表面和内外端壁附近由于二次流动引起流面翘曲时的计算,特别适用于与S1、S₂流面的势流方程相互迭代,求解高R_e值下叶栅流道内的三元粘性流场。更多还原

【Abstract】 In this paper, the differential equations of the boundary layer on two kinds of relative stream surfaces （S₁ and S₂ stream surfaces） are established in a relatively orthogonal curviliear coordinate system. The equations can be used not only to describe the general behaviors of the boundary layer in a stator and a rotor blade passage, but also to calculate the skewings near blade surface and endwalls due to a secondary flow. They are especially suitable for iterating the equations of the potential flowon S₁ and S₂ stream surfaces to calculatea three-dimensional viscous flow field in a cascade passage on condition that the value of R_e is high.更多还原
