Numerical analysis for viscosity temperature characteristics of abrasive flow finishing on micro-bore nozzle
Abrasive flow machining has become an efficient and economical ultra precision process for machining micro-bore parts.In this paper, aiming at viscosity temperature characteristics of abrasive flow fmishing on micro-bore nozzle, under the guidance of the three governing equations of fluid mechanics theory, mixed phase model and discrete phase model were conducted, FLUENT software was resorted to simulate the discrete and fluid phase numerical characteristics of the solid-liquid two-phase flow field in the nozzle orifice with various field temperature and viscosity of slurry, the mechanism of erosion and wear of particles and effect of different processing parameters on particle erosion rate were uncovered, which provides a theoretical basis for the nozzle structure of abrasive flow machining.
