Effect of Lubrication of Fluid Friction Bearings with Media of Complex Rheology

Abstract:

The paper investigates the two-dimensional flow of an incompressible viscous fluid of complex rheology in the gap between two cylinders with respect to fluid friction bearings. The viscosity of the fluid is defined as a physical quantity field, satisfying the criterion of minimum friction loss approximated as a function of shear-strain rate and pressure. The resulting function is used to calculate the carrying capacity and the friction torque in the bearing. Computer experiment resulted in showing the effect of friction loss lowering due to considering complex rheology of lubricating material.
