| Abstract: | The self-oscillating abrasive water jet (SOAWJ) is a new type of abrasive water jet formed from the combination of self-oscillating water jet and pre-mixed abrasive wter jet. This paper discusses the configuration and operating principle of the SOAWJ nozzle, and analyzes the effects of the pulse frequency and amplitude on the abrasive particle speed in the SOAWJ nozzle. It is experimentally shown that the drilling rate of SOAWJ is about 46% highen than that of the pre-mixed abrasive water jet. |
