Hypersonic laminar viscous flow past spinning cones at angle of attack

Computational results are presented for hypersonic viscous flow past spinning sharp and blunt cones at angle of attack, obtained with a parabolic Navier-Stokes marching code. The code takes into account the asymmetries in the flowfield resulting from spinning motion and computes the asymmetric shock shape, cross-flow and streamwise shear, heat transfer, cross-flow separation, and vortex structure. The Magnus force and moments are also computed. Comparisons are made with other theoretical analyses based on boundary-layer and boundaryregion equations, and an anomaly is discovered in the displacement thickness contribution to the Magnus force when compared with boundary-layer results.
