Embodiment 1
[0037] The number of nozzle unit bodies in this embodiment is three, and each nozzle unit body is provided with an axially symmetric binary half nozzle, and each nozzle unit body is passed through from the inner ring to the outer ring through four center-symmetrical nozzles. The two-element annular slot ejector 3 is also provided with an annular cavity communicating with each nozzle unit body, and the high-energy fluid enters the annular cavity from the through hole of the high-energy fluid inlet section 2 and then flows out The outlet of the nozzle unit body is ejected.
[0038] The numerical simulation results show that, compared with the traditional annular slot ejection, under the premise of achieving the same ejection effect, the space requirement of the distributed annular slot ejector device of this embodiment is smaller. Reduced by more than 30%, the length of the pipe section can be reduced by more than 20%.
