NUMERICAL ANALYSIS OF A VISCOUS TRANSMISSION.

A viscous coupling is a simple device that transmits torque by shearing an oil film between one or more pairs of discs that are moving in relation to one another. Due to their many advantages, viscous couplings are studied in many applications such as fan transmissions in vehicles, pumps, winches, belt conveyors, wind turbines, tunnel boring machines. Using a CFD Software, this study examined how grooves affected the performance of a viscous coupling. The main objective of the reported work is to study the flow of the fluid film, the total temperature and the torque of a viscous coupling that is operating in different conditions.
