摘要：
Self-excited oscillating pulsed cavitation jet is a phenomenon in which cavitation bubbles are generated by oscillation in the unique structural characteristics of the nozzle, and the impact effect of the jet is increased by collapse of the cavitation bubbles. Based on the structure parameters of the traditional Helmholtz and organ pipe single chamber self-excited oscillating pulsed nozzles, Helmholtz + Helmholtz, Organ pipe + Organ pipe and Helmholtz + Organ pipe dual chamber self-excited oscillating pulsed nozzles with different structures are established in series, and VOF (Volume of Fluid) is selected for multiphase transient flow calculation. The external flow field of dual chamber is studied to obtain the best combination nozzle.
