Abstract
Abrasive water suspension jet (AWSJ) has a greater capacity for drilling and cutting than abrasive water injection jet (AWIJ). In the present investigation, the drilling capability of the AWSJ under submerged condition is studied experimentally with specimens of stainless steel at the jetting pressure of 12 MPa and the ambient pressure of 0.1 MPa. Two different aluminum oxides #100 and #220 are used. It is found that the drilling capability decreased steeply with the increase of the standoff distance. The nozzle and the nozzle holder affect the drilling capability of the submerged AWSJ. The grain size of the abrasive also affects the drilling capability of the submerged AWSJ.
