Abstract
In this paper, the problem of near-continuum gas flows over a cylinder is numerically investigated. Three types of boundary conditions for the cylinder surface are adopted: 1) with nonslip and constant temperature surface, 2) velocity slip with a consideration of velocity gradient and temperature jump at the surface, and 3) velocity slip with considerations of both velocity and temperature gradients, along with temperature jump at the surface. Two-dimensional Navier–Stokes equations for compressible flows are adopted with the Roe numerical scheme. The numerical results include flowfield properties, coefficient distributions for surface pressure, friction, heat flux, velocity slip, temperature jump, and total drag. The third type of surface boundary condition does not create significant differences from the second type. Rarefaction effects on the total drag are also investigated.
