摘要

A correlation between spatial linear stability calculations and the onset of transition in compressible jet shear layer was investigated. In the present study, an attempt was made to apply the conventional e~N method to a transition predic- tion of the free shear layer flow in a compressible jet. The mean velocity profiles for a compressible circular jet were experimentally obtained at different downstream locations, which were used as an input to the linear stability calculation code. The growth rates of disturbances from the stability calculation were integrated to obtain and envelope curve.
