The theoretical analysis of drag torques within a two-speed dual clutch transmission is
presented in this article. The numerical models are developed to study the different sources …

Fundamental knowledge of the oil flow in a disengaged wet clutch is essential for optimizing
the cooling performance and the drag losses. However, no fundamental information on the …

The flow field of an open grooved two-disc system was studied. The system includes a
rotating finite disc and a stationary finite disc. The rotating disc has radial grooves. The …

A mathematical model based on continuity and Navier-Stokes equations, considering
laminar flow in the gap between the disks, is presented to estimate the drag torque in open …

The viscous shearing of the cooling oil within disengaged wet clutches causes a substantial
amount of power loss. In order to optimise efficiency, it is the objective of current research to …

A considerable part of the power loss in disengaged wet clutches is caused by viscous
shearing of the cooling oil between the clutch discs. Reducing this drag loss as far as …

Fundamental knowledge of wet clutches' drag loss behavior is essential for designing low-
loss clutch systems. In contrast to the widely investigated injection lubrication, more …

The undesired Drag Torque (DT) which is developed due to the shearing of fluid film in
between the disk and separator plate reduces the efficiency of a transmission and increases …

When the clutch is in disengaged condition, ideally no torque should be transmitted.
However, in reality, the relative motion between the disks causes viscous shearing of fluids …

The relative motion between the friction and separate plates in a disengaged wet clutch
causes viscous drag torque when the lubrication fluid flows through the clearance …
