Numerical simulation analysis of the parts of the fifth-order surge tube

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.
