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

Figure 25

Spreading rate of the shear layer versus the chamber/injectant or chamber/inner-jet density ratio for single and coaxial jets compared with different predictions for planar shear layers. For the coaxial data, the chamber pressure increases from sub- to near- and to supercritical conditions in the direction of the arrow.
