The problem of relaminarization of supersonic turbulent boundary layers on axisymmetric bodies under flight conditions in the presence of heat transfer

摘要

Analysis is made of the results of investigation of the problem of relaminarization of turbulent boundary layers under conditions of different kinds of stimulation of the field of flow. Results are given of flight aerophysical experiments involving the effect of relaminarization in a supersonic turbulent boundary layer for Re{sub})(L,∞) ≤ 10{sup}8, M{sub}∞ ≤ 4.5, and an acceleration a ≤ 32g under conditions of aerodynamic heating. Quantitative data are given on the gradient criteria of stability of two types at starting points of relaminarization under flight conditions.
