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

Figure 22

This figure shows comparison of the present coaxial-jet dark-core length measurements with all other relevant core length data available in the literature versus momentum flux ratio. Amongst the data reported by others, Eroglu et al. [47], Englebert et al. [48], and Woodward [50] are two-phase flows and the rest are single phase. The range of core length for cryogenic single jet (LN₂/GN₂) is also shown at the left margin. Davis and Chehroudi [42, 43].
