Axisymmetric Turbulent Boundary Layer on the Cylindrical Portion of an Afterbody Test Model

摘要

Experiments were conducted to study the characteristics and the growth of an axisymmetric turbulent boundary layer on the central cylindrical portion of a model in the presence of a circular arc forebody, an afterbody and a high pressure cold air jet issuing from the base. An 80mm Max. dia model was tested at the freestream velocities of 12.8 and 21.5 m/sec and at jet pressure ratios of 1.0 (jet-off), 1.26 and 1.54. The results of the experimental study are described.
