通过对振荡腔内流体压力的测定、非淹没射流条件下影响脉冲振荡的参数以及脉冲射流的相关特性、非淹没条件下自激振荡脉冲射流的冲蚀效果、碰撞壁碰撞区域的磨损对自激振荡脉冲射流影响的试验研究。实验表明自激振荡脉冲射流在相同条件下与常规的连续射流相比,射流的峰值压力,冲蚀体积和射流的有效靶距均得到明显的提高。
Through the determination of the fluid pressure in the oscillating cavity, the parameters that influence the pulse oscillation in the non-submerged jet and the characteristics of the pulse jet, the erosion effect of the self-excited oscillating pulse jet under non-submerged conditions, Experimental Study on the Influence of Oscillating Pulsed Jet. Experiments show that under the same conditions, the self-excited oscillating pulse jet has significantly higher peak pressure, erosion volume and jet effective target distance compared with the conventional continuous jet.
