后混合水射流扇形混合喷嘴的设计与流场数值模拟
Fan-shaped mixed nozzle of rear mixed water jet and numerical simulation of flow field
摘要
Abstract
This paper is aimed at an improved performance of surface treatment of rearmixed water jet shot peening.The study involves the numerical simulation of the liquid-solid two-phase flow field of nozzle using Fluent software after the designing of rearmixed water jet nozzle with fan-shaped mixed nozzle structure based on the rearmixed water jet nozzle used for cutting.The numerical simulation uses the Euler model for the multiphase flow;and the k-ε model for turbulence eddy viscosity model,followed by an analysis of the influence of V-shaped angle of fan-shaped mixed nozzle on both jet diffusion width and axial velocity.The result shows that fan-shaped mixed nozzle performs at the best V-shaped angle of 45 °,in which case,solid projectile flow field along groove direction has the diffusion width of 15.39 mm and projectile flow field has the axial velocity of 52.70 m/s,as occurs with 10 mm target distance.关键词
