Summary: An efficient multigrid, central difference, finite volume Navier-Stokes solver is used to study the ``natural occurrence'' of steady, anomalous, asymmetric separated ``locally conical'' flow solutions at high incidence and at supersonic speeds. The study documents the regime in which asymmetric conical flows are likely to occur 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 and is exhibited for a variety of cross- sectional shapes. The elimination of asymmetric flow behavior with the addition of strakes is also demonstrated. This paper also presents a parabolized Navier-Stokes solution for a three-dimensional ogive cylinder body exhibiting asymmetric flow behavior.
