Heat-transfer on yawed infinite cylinders in a hypersonic stream

Abstract

Nonequilibrium air flow past the nose of a yawed infinite elliptical cylinder in flight at an altitudeH=66 km and velocityV??=6500 m/s is investigated on the basis of the thin viscous shock layer equations. The ellipticity coefficient δ and the yaw angle χ are varied and calculations are carried out for both absolutely catalytic and absolutely noncatalytic body surfaces. The values of the parameter δ corresponding to the lowest maximum surface temperature are determined.
