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 …

In the design of high pressure piston pumps/motors, some manufacturers use pistons which
have grooves being cut along the piston length, while others do not use grooves at all. The …

A model is developed to investigate the effect of radial grooves and waffle-shape grooves on
the performance of a wet clutch. Three-dimensional formulation of the governing equations …

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 …

Most state-of-the-art natural gas-fired combined cycle (NGCC) plants are triple-pressure
reheat cycles with efficiencies close to 60%. However, with carbon capture and storage, the …

In wet clutches, load-independent drag losses occur in the disengaged state and under
differential speed due to fluid shearing. The drag torque of a wet clutch can be determined …

Within disengaged wet-running multi-plate clutches a certain drag torque is generated as a
result of the differential speed between the discs. These losses can be reduced providing …

Purpose The purpose of this paper is to reduce the drag loss and study the effects of
operating conditions and groove parameters such as flow rate and temperature of automatic …

The current design of hydro-viscous clutch (HVC) in tracked vehicle fan transmission mainly
focuses on high-speed and high power. However, the fluid torque under the influence of …

Featured Application The findings can be used to prevent or predict cavitation in hydraulic
machinery, such as hydro-viscous clutches, wet clutches, disk turbines, and disk motor …
