Paper Abstract

Fluent jet polishing is a new precision optical surface machining method. To improve the removal efficiency of jet machining, a rectangular-nozzle has been designed to take the place of the traditional round nozzle. According to the principles of fluid dynamics, the flow field characteristic of rectangular-nozzle structure was analyzed theoretically. The flow field distribution of different models is calculated. The shape of the rectangular nozzle has an important influence on the jet flow field distribution. So an analysis model is established to discuss the fluid field characteristics of different rectangular-nozzle structure. The impact process of several typical rectangular-nozzle is simulated by FLUENT, and the flow jet pressure and velocity distribution on the workpiece have been obtained. Then the influence on the dynamic characteristics of different impact angle is analyzed, and the corresponding rectangular-nozzle flow field distribution features are calculated by changing the impact angle.
