| 内容記述 | Experimental investigations were conducted to determine the aerodynamic performance and noise generation characteristics of five ejectors having subsonic secondary flow. Primary nozzles with equal exit area for Mach numbers 1, 1.5, 2, 2.5, and 3 produced a variety of noise and pumping effects. The pumping capacity, specific power, and noise generation of the Mach 1 nozzle was the highest and its mass augmentation was the lowest among the nozzles tested. The Mach 3 nozzle was found superior in mass augmentation and it also produced the lowest noise, however its pumping capacity and specific power was the lowest. |
