Recent Experimental Efforts on High-Pressure Supercritical Injection for Liquid Rockets and Their Implications

Figure 14

Interaction of acoustic waves with a single round liquid nitrogen jet injected into gaseous nitrogen at a range of chamber pressures from sub- to supercritical conditions. (a) Top images show front view; only one acoustic driver located at the left of the jet. The set of images shifted downward are when the acoustic field is turned on as indicated. (b) Bottom images show side views of the same jet (the same acoustic driver is located behind this page). is the reduced chamber pressure (i.e., chamber pressure divided by the critical temperature of the injected nitrogen).
