A Preliminary Investigation of the Singular Behavior of Fluids near a Sliding Corner.

Abstract

This paper describes the application of a semidirect method to the calculation of the flow near a sliding corner. On a set of successively refined grids the Navier-Stokes equations modeling the steady state viscous, incompressible, low Reynolds number flow are solved in terms of the vorticity and stream function in Cartesian coordinates for a slab geometry. The calculated flow field allows preliminary estimate of the nature of the flow at the sliding corner.
