Embodiment 1
[0037] The number of nozzle units in this embodiment is 8, and each nozzle unit is provided with a binary and a half nozzle, with 4 nozzle units in the upper half and 4 other nozzle units symmetrically distributed in the lower half , the four nozzle units in the upper half are connected and supported by a hollow reinforcing rib that penetrates up and down on the symmetry line, and the four nozzle units in the lower half are respectively connected and supported by the symmetry line Another symmetrical hollow-shaped reinforcing rib connected and supported up and down; the binary nozzle injector 3 is also provided with an annular channel communicating with each nozzle unit, and the high-energy fluid flows from the high-energy fluid inlet section 2 After the through hole enters the annular channel, it is sprayed out from the outlet of the nozzle unit body.
[0038]Numerical simulation results show that, compared with the traditional annular seam ejection, the distributed binary no...
