A numerical simulation was carried out to examine the effect of radial and/or circumferential grooves on the frictional surface temperature and torque response in a multidisk wet clutch. The modified Reynolds equation for hydrodynamic lubrication and heat conduction equation for heat transfer were solved by SOR and ADI methods, respectively. The real contact area was given by Greenwoods and Williamson model, the contact pressure was assumed proportional to the real contact area. The simulation results show that the temperature at the surface material can be better controlled by the simultaneous use of radial and circumferential grooving.It was also shown that grooving enhances the torque response in the case of low permeable friction material.
