To study the effect of grooves on the cooling performance of wet clutches

a simulation model of wet clutches was established

with use of STAR-CCM+ software. The model is based on the k-ε two-layer turbulence model and the euler volume of fluent model (VOF) model. Without changing the cross-sectional area of the groove flow

the shape of the groove was optimized

and simulation analysis was conducted using STAR-CCM+ to obtain the flow field and temperature distribution in the radial groove. The results show that under the same cross-sectional area of the groove flow and the same coolant flow rate

the cooling effect of the optimized groove structure is significantly improved. On this basis

in-depth research was conducted on the groove structure to obtain the cooling effect under different flow rates and rotation-speed differences

providing potential theoretical evidences for the design and optimization of wet clutch friction plates.
