Boundary-Layer Transition on Blunt Bodies.

Abstract

The results of linear stability theory have been used to predict the location of boundary-layer transition, with emphasis on including the effects of surface roughness and axisymmetric geometry. Both of these parameters are important in determining transition on re-entry vehicles. The effects of surface roughness were included by means of a 'turbulent sublayer' model which attributes the effects of roughness to an alteration in the mean velocity profile. Axisymmetric effects were included by a proper consideration of the growth rate of the boundary-layer thickness.
