Numerical simulation analysis of large eddy simulation for T-tube based on solid-liquid two-phase abrasive flow

摘要：

　　As a kind of nano machining technology, abrasive flow polishing technology plays an important role in precision machining region.As an important numerical simulation method in fluid mechanics, large eddy numerical simulation method has become an important method for many scholars to study abrasive grain polishing technology.In this paper, the use of fluid mechanics software FLUENT and selected Mixture mixed model.Based on the theory of solid-liquid two-phase flow dynamics, the large-eddy numerical simulation method was used to study the polishing process of T-tube abrasive flow, and the micro-machining mechanism of abrasive-polished workpiece was discussed.The influence of the different inlet velocities on the polishing effect of the abrasive grains was discussed by analyzing the numerical simulation results of the different inlet velocities of the abrasive grains during the processing of the T-tube.
