Lubrication Theory for Micropolar Fluids

Abstract

The equations governing the flow of a fluid with rigid, spherical substructure are summarized. A two-dimensional flow field is considered and applied to the geometry of a slider bearing. Order-of-magnitude arguments are used which reduce the governing equations to a system of coupled, linear, ordinary differential equations. The equations are solved subject to appropriate boundary conditions and the effects of substructure discussed with the help of a specific numerical example.

“…Many authors have assumed that special class of fluids, see Kline and Allen [9], Ahmadi [11], Allen and Kline [12], and Rees and Bassom [13].…”

Effect of Elasticity on Capillary Compensated Flexible Multi-recess Hydrostatic Journal Bearing Operating with Micropolar Lubricant

“…A number of studies [1][2][3][4][5][6][7][8][9][10] on micropolar lubrication have been reported. Das et al [11] have presented the dynamic characteristics of hydrodynamic journal bearings lubricated with micropolar fluids.…”

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

“…In case of Newtonian fluids it is observed that the increase in load carrying capacity, lower coefficient of friction and delayed time of approach by keeping the viscosity constant. Many investigators [13][14][15][16][17][18][19][20][21] reported that the uses of micropolar fluids in different bearing systems which results in decrease in the load carrying capacity and improve in squeeze time. In general, viscosity of all the fluids decreases with increase in temperature.…”
