In order to study the influence of the structural and operating parameters on device performance of the self-excited pulsed jet in low-press and Amount-flux, a great deal of experiments on structural and operating parameters of the self-excited pulsed jet was carried out by independently developed testing system. Under the certain upper nozzle diameter and cavity diameter, the changes of the lower nozzle diameter and cavity length and working pressure have an effect on the hitting power of the pulsing jet and pulsing effect. Experimental results showed that for the different lower nozzle diameter and under each working pressure the influence of the cavity length changes on the hitting power is different, there is the optimal range of cavity length and working pressure while the lower diameter is fixed, and with the increase of the lower nozzle diameter, the range of the optimal cavity length and working pressure also has a gradually increasing trend.
