Vortex Generation on the Surface of Bodies in the Vortex Method.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1997 The aim of the present work was to analyze the generation of vorticity on the surface of bodies. The fluid flow examined is viscous incompressible fluid and the local solution near the surface of bodies is considered. The solutions of the two-dimensional Navier-Stokes equation are constructed by means of a boundary layer equation for three initial ...
