Multi-frictional disks are employed to transmit the torque in speeding wet clutch, and the oil thickness within frictional disks could be adjusted for practical output speeding. As oil combined with a-hydrocarbon or polyester is getting widely used as lubricant and the speeding wet clutch works within hydrodynamic lubrication, mixture lubrication, boundary lubrication and contact situation, established the thermal analysis model for investigating the behavior of frictional disks in speeding wet clutch, which covers the power-law fluid model, Patir-Cheng average flow model,GT asperity contact-model, oil film inertia and heat effects, mean energy equation, and heat conduction equation. The formulas in the model are deduced. The numeral calculation and analysis for hydrodynamic lubrication and mixture lubrication are executed. Relationships and variations among transmitting torque, mean push pressure, output speed, and load are presented. Thermal effect should be considered during the hydrodynamic lubricat
