Control Mechanism of Particle Flow in the Weak Liquid Metal Flow Field on Non-Uniform Curvature Surface Based on Lippmann Model

In order to realize the uniform distribution in abrasive flow polishing of titanium alloy workpiece with curved surface, a novel method based on liquid metal-abrasive machining technology is proposed this study. Based SST k - ? model, Preston model and fluid particle tracking COMSOL software employed study dynamic characteristics under different AC electric field conditions, two-phase used simulate state, movement metal particles surface varitation Pv value near-wall region. It found from numerical simulation results that average strong 23,718.8 W/m 2 , weak 5,427.3 . By assistance filed voltage 36 V, be 10,948.6 an increase 101.7%. Therefore, properly control strength, can controlled, hence improving uniformity turbulent kinetic energy processing quality.
