Recent Experimental Efforts on High-Pressure Supercritical Injection for Liquid Rockets and Their Implications
Figure 15
Regimes discussed by Rockwell [37] shown on an excitation Strouhal number versus the jet Reynolds number plot. The small solid rectangle to the right indicates the approximate region in which the Chehroudi jet data lies when excitation is at 4800 Hz. The curve within this rectangle shows the approximate path as flow rate is increased from the lowest to the highest values, all at supercritical chamber pressures. Similar region for the 2700 Hz excitation is shown as a dashed rectangle. Chehroudi and Talley [36].
