Squeeze film characteristics of long partial journal bearings lubricated with couple stress fluids

Effect of Magnetohydrodynamic Couple Stresses on Dynamic Characteristics of Exponential Slider Bearing

“…The Stokes theory allows for polar effects such as the presence of couple stresses, body couples and non-symmetric stress tensors. On the basis of Stokes theory, many researchers studied effect of couple stress on bearing characteristics such as slider bearing by Ramanaiah and Sarkar [8], short journal bearing by Ayyappa et al [9], circular stepped plates by Naduvinamani and Siddangouda [10] and long partial journal bearing by Lin [11]. According to the results obtained, the use of non-Newtonian fluid enhances the bearing performance RESEARCH characteristics.…”

Multigrid Method for the Solution of Combined Effect of Viscosity Variation and Surface Roughness on the Squeeze Film Lubrication of Journal Bearings

“…Lin 2 studied the static and dynamic behaviours of squeeze films using a couple stress fluids in a short journal bearing. The couple stress fluid model were studied by Lin et al [3][4][5] , Wang et al 6 , Guha et al 7 and many researchers have analysed the hydrodynamic lubrication problems with different journal bearing geometries. Spikes 8 showed the behaviour of lubricants in contacts, current understanding and future possibilities.…”

Bifuraction Analysis of Hydrodynamic Plain Journal Bearing Lubricated With Couple Stress Fluid

“…The Stokes model provides a convenient means of investigating particle-size effects in couplestress fluids and has been successfully applied to analyse fluid phenomena in a wide variety of scientific and engineering applications. For example, in 1997, Lin [4] used the Stokes micro-continuum model to investigate the squeeze film characteristics of long partial journal bearings lubricated with a couple-stress fluid. The same author [5] also applied the model to explore the static and dynamic behaviour of pure squeeze films in short journal bearings lubricated with a couple-stress fluid.…”
