Asymmetric separated flows over slender bodies at supersonic speeds

Abstract An efficient multigrid, central difference, finite volume Navier-Stokes solver is used to study the natural occurrence of steady, anomalous, asymmetric separated flow solutions at high incidence and at supersonic speeds. The regime in which asymmetric conical flows are likely to occur is documented as a function of Mach number and cone angle. It is also shown that the existence of asymmetric flows is not unique to circular cones but is exhibited for a variety of cross-sectional shapes. A parabolized Navier-Stokes solution is presented for a three-dimensional body exhibiting asymmetric flow behavior.
