摘要：
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 Eases are presented.
