In order to investigate the effect of abrasive flow on the polishing effect of mutant tube parts, this paper chooses the fifth-order mutant tube parts as the research object, and the abrasive flow analyzes and analyzes the polishing process of the fifth-order mutant tube parts, and discusses the micro- Processing mechanism. Based on the analysis of the dynamic pressure, velocity and turbulence kinetic energy distribution of the fifth-order sudden change of the flow conditions, the numerical simulation results of the fifth-order abrupt change of the abrasive flow were analyzed, and the different pressure conditions of the abrasive inlet Effect of abrasive flow polishing.
Solid-liquid two-phase abrasive flow machining is a method to effectively polish the surface of Special-shaped surface parts. Based on the processing characteristics of the abrasive flow machining. The standard model and the pressure-coupled SIMPLEC algorithm are used. The shear force and velocity of the near-wall surface of the runner of the solid-liquid two-phase abrasive machining with different inlet pressure are analyzed. The numerical simulation results show that the inlet pressure has little effect on the velocity, and the shear force has a linear relationship with the inlet pressure. To obtain a better polishing effect, the outlet pressure can be appropriately increased.
