Recent Experimental Efforts on High-Pressure Supercritical Injection for Liquid Rockets and Their Implications
Figure 30
Instant images of sub-, near-, and supercritical impinging jets for into (room temperature) injection by Chehroudi. The last two rows show the same injector in the first two rows but viewed at a 90-degree angle. ; from lower right to upper left, . For nitrogen: ; . Re = 25,000 to 70,000; holes’ length-to-diameter () of ~100; no cavitation; injection velocity: 10–15 m/s. Chehroudi [56].
