The Study on Cavitation Phenomena of Zoom Nozzle Based on Orthogonal Experimental and Spraying Mechanics

Abstract:

Abstract: The simulation model of zoom nozzle was established in this article.The numerical simulation of flow field in the zoom nozzle was completed with the Fluent software and based on orthogonal experimental method the structure size optimization of the nozzle was completed too.The results showed that the cavitation phenomenon is easy to form near the transition area of the cylindrical section and expansion section of the nozzle.Using orthogonal experimental method,we can achieve structure size optimization of the nozzle from reducing cavitation rate and increase the distance that emergence point of maximum cavitation rate with the cylindrical section of nozzle.
