Abstract | The problem of near continuum gas flows over a sphere is investigated numerically. Three types of surface boundary conditions are adopted: 1) non-slip and constant temperature surface; 2) velocity slip with velocity gradient but without temperature gradient along the surface; and 3) velocity slip with considerations of both velocity gradient (along the direction normal to the surface), as well as temperature gradient along the surface. Navier-Stokes equations forcompressible flows are solved with the Roe scheme. The numerical results include coefficient distributions for surface pressure, friction, heat flux, velocity slip, and temperature jump. The third type surface boundary condition does not create significant differences from the second type. |
