Thermohydrodynamic Lubrication Of Asymmetric Rollers By Bingham Plastic Fluid

Abstract

This research work focuses on qualitative analysis of hydrodynamic lubrication of
asymmetric rollers under usual boundary conditions for a heavily loaded rigid system where
the viscosity of non-Newtonian incompressible Bingham plastic fluid is assumed to vary with
hydrodynamic pressure. The fluid flow governing equations such as continuity with
momentum equation and thermal energy equation are solved analytically first and then
numerically using MATLAB. Some important characteristics of the roller bearings are
elaborated through graphs and tables. Finally, it is concluded that a significant change in
pressure, temperature, load and traction with Newtonian and non-Newtonian fluids is
observed. The results are in good agreement with the results available in literature.
