In this paper we are consider a major program of research into the effects on transition of the vibrational and dissociational relaxation processes that occur in high-enthalpy flows are studied. Relaxation effects are investigate to influence transition significantly, Reynolds number of flows over slender cones to be increased by almost an order of magnitude. The relationship between absorption of acoustic waves by relaxation and their amplification in the flow over a swept cylinder shows that very significant transition delay may occur through relaxation effects.
