COMPRESSIBLE TURBULENT BOUNDARY-LAYER - SURVEY OF METHODS OF ANALYSISAND RESULTS

This paper gives a survey of methods and results on turbulent compress ible boundary layer characteristics. Properties are deduced from the k nowledge of different moments. Hot wire anemometry and laser Doppler v elocimetry are combined in the so-called ''strong Reynolds analogy'' b ased on a mixing length concept, and generalized to the case of a surf ace heat flux. This allows one to determine the thermal field from the measured velocity field. Recent experimental data lead to making new conclusions concerning the validity of the analytical relations. These relations express links between compressible and incompressible bound ary layer properties. New relations are also added.
