Abstract
The effect of secondary gas injection on the flow through an axisymmetric Mach 2 nozzle is studied experimentally. The experiments were conducted for a nozzle pressure ratio of 5. The secondary injection locations chosen for this study were Ls = 0.5Ld and 0.75Ld, and the secondary gas was injected at secondary pressure ratios (SPR) 0.5, 1.0, and 1.5. It is found that for injection at 0.5 Ld, the flow emanating is not deflected for all SPRs. For injection at 0.75 Ld, the flow is deflected by about 5.50, 5.50 and 100, for SPRs 0.5, 1.0, and 1.5, respectively. These flow deflections are observed only in the plane of injection. The effect of secondary injection was not observed in the plane normal to the secondary injection.

期刊介绍：
Visualization is an interdisciplinary imaging science devoted to making the invisible visible through the techniques of experimental visualization and computer-aided visualization.
The scope of the Journal is to provide a place to exchange information on the latest visualization technology and its application by the presentation of latest papers of both researchers and technicians.
