基于 FLUENT 的人工淹没射流喷嘴流场仿真
Flow Field Simulation of Artificial Submerged Jet Nozzle Based on FLUENT
摘要
Abstract
According to the characteristics of Fluent fluid simulation software and flow field of artificial submerged jet nozzle ,based on the theory of hydromechanics , simulation research of artificial submerged jet nozzle was done .Through calculation of numerical simulation , its pressure distribution , velocity distribution and static pressure distribution diagram were got .The simulation results showed that maximum velocity existed in cylindrical segment in artificial submerged jet nozzle , the jet produced strong shearing action in the outlet of cylindrical section and the surrounding water , uneven velocity and pulsation were generated and negative pres-sure area appeared obviously in cylindrical section outlet , all of which provided favorable conditions for the generation of cavitation .关键词
