| Abstract: | The simulation study of the jet process of the organ-pipe SRC jet nozzle was carried out by using CFD and plot analysis software Fluent 6.0,Gambit 2.0,Tecplot 9.0.The distribution maps of flow velocity and pressure in the different unit organ-pipe SRC jet nozzles had been obtained by using the method of model building and numerical calculation.the results of all the designed SRC jet nozzle can work well in SRC water jet had been analyzed.The formulas determining structural parameters of an organ-pipe resonator had been verified,and the effects of the structural parameters of an organ-pipe resonator on SRC water jet were studied,so that the simulation study would provide new ways for the optimum design of SRC jet nozzles. |
