In oder to understand the distribution of temperature and pressure in a mechanical seal cavity, Fluent software was used to carry out a numerical simulation on temperature and pressure. Based on Navier-Stokes equations and the standard turbulent model, the temperature and flow fields for a mechanical seal ring were simulated. The results prove that the temperature in the mechanical seal cavity has little change and the temperature on the mechanical seal wall has greater change. The velocity near the meachanical seal wall is slower than that in cavity. The velocity distribution is linear and continual. The plot of pressure is nearly balanced at axis. There is a partical pressure change when the area of the cross section of the mechanical seal cavity changes suddenly. By comparing the calculated results with that from experiment, the error range is about 6% to 17.5%, which is coincident with the actual situation. It shows that numerical simulation can be carried out on the visual calculation for the invisible change in the flow field.
