湍流对磨料水射流中磨料颗粒受力的影响
Effects of Turbulence on Drag Force of Abrasive Particles in Abrasive Water Jetting
摘要
Abstract
The flow over a stationary spherical abrasive particle was studied numerically to analyze the effects of turbulent parameters（turbulence intensity and turbulent viscosity ratio） on the drag force of an abrasive particle.Several turbulence models were verified by using the models to analyze the submerged impinging jet.The Reynolds stress model was chosen to simulate the turbulent flow over the abrasive particle.The turbulence intensity varied from 5% to 70% and the turbulent viscosity ratio varied from 1 to 1200.Conclusions can be drawn from the simulation that with the increase of turbulence intensity,the drag force on the abrasive particle increases and with the increase of turbulent viscosity ratio the drag force on the abrasive particle also increases.关键词
