Exploratory development of hypersonic heat transfer and thermomechanical ablation of advanced materials: Review of European progress

The overall program study was in three specific areas: (1) evaluation of wind tunnel test data, (2) rough wall boundary layer transition, and (3) review of European turbulent boundary layer state of the art. The first two topics are included in Volume I and the last topic comprises Volume II. The study presented in Volume II is a result of a subcontract with the Aeronautical Research Institute of Sweden to review current European progress in turbulent boundary layer prediction methods. In particular, work related to nosetip boundary layer phenomenology, including the effects of roughness, body curvature, separation, and reattachment are discussed.
