Abstract

For the axisymmetric base flow problem in presence of a jet, a systematic study is carried out taking into account all essential physical parameters. Using the method of characteristi cs for the inviscid outer flow and the method of Korst for the turbulent shear layers, the influence of the approaching boundary layer is introduced by the concepts of equivalent bleed and origin shift, and the ONERA angular criterion is used for the recorepression process. A modification of the ONERA criterion for the two-stream recompression is proposed. The results are thoroughly discussed and compared with experiments, and estimations of the Reynolds number influence are presented.
