Experimental Study on Fluid Coupling by using Various Working Fluids

Abstract

Fluid coupling, this is useful to transfer Mechanical Power or Torque from one shaft to another shaft without
using any mechanical devices like gears or belt drives etc. It works on hydrodynamic principle,it has been used in automobile
transmission alternative to clutch. It is very important to transfer power very efficiently to avoid power losses. Efficiency of
power transfer mostly depends on properties of the working fluid. In this paper,i would like to discuss a fluid coupling model
with two pumps and one turbine (i.e hydraulic coupling) and tested with different working fluids (Multi Grade Oils).
