双筒水流中单颗粒差异旋转惯性力的数值模拟
Numerical Simulation Which is Single Particle in the Flow of Binoculars Suffered Difference Rotational Inertia Force
摘要
Abstract
On the basis of the physical model experiment,using DPM model to simulate the Taylor vortex cell experiments and using Moving Mesh in binoculars and concentric rotating flow simulation,the paper discussed the motion characteristics and force law of single particles. Simulation results show that a)in the rotation system,the smaller the flow rate is,the more obvious trend of single particles centrifugal movement will be;b)When the continuous rotation of the inner cylinder,the outer cylinder is stationary,difference rotational inertia force is less than centrifugal force in numerical,but they belong to the same orders of magnitude and in the same direction,single particle do centrif-ugal movement,when the continuous rotation of the inner cylinder and then still and outer cylinder is stationary,differences in rotational iner-tia force and the centrifugal force are in the opposite direction,differences in rotational inertia force is greater than centrifugal force,both dif-fer an order of magnitude,single particle do centripetal movement;c)Whether the inner cylinder is continuous rotation or stationary after the first rotation,Reynolds gradually decrease and the radial force affects the single particle state of motion.关键词
