The secondary flow about a circular cylinder mounted normal to a flat plate
Abstract
Three-dimensional steady incompressible viscous flows about a circular cylinder being mounted with its axis normal to a flat plate were studied numerically. First a finite-difference method using the equations in terms of the pressure, the velocity and the vorticity was proposed. In the method the cells in an orthogonal curvilinear coordinate system are used, which consists of the equi-potential lines and the streamlines for a two-dimensional potential flow past a circular cylinder in a uniform flow. It is convenient to use such coordinates to prescribe the initial and outer boundary conditions and to show the secondary flows. Then the flow patterns for the Reynolds numbers 100 and 500 were calculated. The flow separation and the horseshoe vortex at the front of cylinder, another vortex generating near the side corner, and the shearing stress at the flat plate and the cylinder walls were discussed.
