Abstract
The needle valve body nozzle hole is taken as the research object. The solid-liquid two-phase flow model is used to simulate the flow field distribution of the abrasive slurry jet extrusion process. The effects of different processing parameters such as pressure, abrasive volume fraction, abrasive particle size and other factors on the extrusion grinding process were explored through simulation experiments. Through the analysis and calculation, the pressure velocity cloud diagram inside the nozzle hole and the curve at the central axis of the nozzle hole are obtained. The results show that the pressure has a significant influence on the extrusion grinding process. A certain amount of pressure contributes to the grinding of the needle body; an excessive abrasive volume fraction affects the grinding effect; the abrasive particle size has little effect on the grinding within a certain range.
