Abstract

The granularity of abrasive jet is closely related to the jet force. The paper uses the FLUENT software simulation technology to analyze the flow field structure under the condition of jet with different abrasive granularity. It is found that single particle momentum increases along with the growth of granularity, so does the amplification. But this trend would stop when the granularity reaches certain value. Momentum reflects the strike capability, so, there is an upper limit correspondingly, inferring the abrasive granularity contributing to abrasive jet force. For certain conditions of abrasive jet, optimal granularity range exists, which brings an optimal jet force. The optimal granularity shall be related to the nozzle structure, jet pressure and particle material properties. The research provides an effective reference for the mastery of the motion law of abrasive jet and optimizing the abrasive jet technology.
