| Abstract: | Based on the computational fluid dynamics(CFD) theory and numerical simulation methods,the seal cavity flow field for the bellows mechanical seal under complex working conditions such as the high temperature,high pressure and high-speed was numerically simulated with analysis,and the temperature field,pressure field,turbulent kinetic energy and the flow field vorticity distribution of the medium in the seal cavity were obtained.The fluid flow in the seal cavity and the heat transfer dynamic characteristics were analyzed.References are provided for numerical method of heat flow solid coupling in temperature field of static and dynamic rings. |
