On the Generation of Vortical Flow at Hypersonic Speeds over Elliptical Cones,

Abstract

A method for calculating the hypersonic slip flow around slender elliptic cones at slight angle of attack is developed. The governing equations are derived from the Navier-Stokes equations and the energy equation by an order of magnitude analysis. There results a system of partial nonlinear parabolic differential equations for the flow variables of the shock formation regime. The system is integrated by means of an explicit finite-difference scheme and the results so obtained are compared with experimental data. Finally the influence of the elliptic cross section geometry as well as the influence of the angle of attack on the flow field properties with particular attention on the cross flow are investigated.
