在Stokes近似的基础上，研究了带缝隙平板的二维慢滞流问题。通过求解一对Riemann-Hilbert问题所确定的两个解析函数，得到闭合形式的流场。计算了通过缝隙的流量和板上的应力分布。还确定了流动的特征，包括尖边附近的局部行为，以及粘性涡旋和鞍状停滞点的形成。给出了几种典型情况下的流线型。
Two-dimensional slow stagnation flow towards a plate with a slit is investigated on the basis of the Stokes approximation. The flow fileds are obtained in a closed form by finding two analytic functions which are determined by solving a pair of Riemann-Hilbert problems. The discharge through the slit and the stress distributions on the plate are calculated. The features of the flow including the local behavior near a sharp edge as well as the formation of viscous eddies and saddle stagnation points are also determined. The streamline patterns for some typical cases are presented.
