... condition, as shown in Fig. 1 , no torque should be transmitted. However, in reality the relative motion between the FD's and the SD's causes viscous shearing of fluids film in the gap between the disks. Fluids refer to the ATF and the mist. This results in a drag torque on both the disks. Fig. 1...

.... The results reveal that air enters the clearance at a critical rotational speed, which causes the drag torque to sharply decrease. The aeration mode and flow pattern are obtained via simulations. The rotational speed of the separator plate has a significant effect on the aeration, including the speed...
