Abstract

The lubricant flow field between the disks of the wet friction pair has been simulated under different lubricant inlet flow rate. The temperature changing on the surfaces of the disks during the wet friction pair operation is investigated. The temperature curve which was exported from the thermo-mechanical coupling simulation for the wet friction pair, is used to define the thermal field of the lubricant flow calculation filed. The viscosity-temperature characteristics of the lubricant is considered in this research as well. The simulation results of the lubricant flow fluid based on the different temperature and different flow velocity distribution show that grooves effect is the very important factor of the lubricant flow fluid. It is found that the flow velocity in the radial grooves and the zone near the walls contact to friction disk which has been grooved is larger while the temperature is lower. It is also shown that the temperature field and flow velocity field are distributing circularly and the closer to the outer edge the higher the flow rate and the higher the temperature is.
