Analysis of composite flow field characteristics in fluid jet polishing

摘要

Fluid jet polishing is an effective ultra-smooth surface processing technology. It can be targeted to remove high-frequency surface defects. Removal efficiency is directly related to the speed of flow field, therefore it is necessary to further analyze the composite flow field distribution characteristics. Aiming at the characteristics of composite flow field, theoretical and modeling research was conducted. FLUENT is used to simulate composite jet flow field. The fluid jet velocity and pressure distribution curve on the workpiece wall have been obtained.
