Aerothermal Problems Associated with Viscous/Inviscid Interaction over Hypersonic Flight Vehicles

摘要: In recent years, there has been a resurgence of interest in the development hypersonic vehicles whose designs are significantly more sophisticated than essentially ballistic re-entry which have constructed and flown to date. assessing prediction techniques associated with design systems like trans-atmospheric vehicle (TAV), orbital transfer (AOTV), number designed be highly maneuverable at speeds, it become evident that important aerothermal problems must addressed. Such include low density non-equilibrium flows transition regime, turbulence turbulent boundary layer shear strong pressure gradients, reacting layers over ablating transpiration-cooled surfaces. However, both laminar flows, classes viscous/inviscid interaction or shock/boundary represent those create most serious load and, same time, difficult compute accuracy.
