Impinging of Slow Stagnation Flows Near a Slit
Two-dimensional impinging of slow stagnation flows near a slit is investigated using the Stokes approximation.
For the arbitrary combination of their strengths and centerline shifts, the flow is described using two complex analytic
functions which are analytically determined so as to satisfy the boundary conditions. The streamline patterns for the
representative cases, the flow behavior near the sharp edges, and the stress distributions on the plates are calculated. The
results show that the flow separates horizontally from the edges and the saddle stagnation point lies on the slit or on the side
of the plates.
