| Abstract: | In this work,the numerical calculation model for the flow area of the single-side dry scroll vacuum pump is established.The numerical simulation of the transient flow inside the single-side dry scroll vacuum pump was performed based on the CFD general software ANSYS-CFX and dynamics mesh method.The working process of the pump was also analyzed,especially the thermal field distribution in the pump under under-compression or over-compression.This work provides a meaningful exploration for the further study of the theory and design of dry scroll vacuum pump. |
