Abstract
Purpose
– The purpose of this paper is to consider magnetohydrodynamic (MHD) squeeze film characteristics between finite porous parallel rectangular plates with surface roughness.
Design/methodology/approach
– Based upon the MHD theory, this paper analyzes the surface roughness effect squeeze film characteristics between finite porous parallel rectangular plates lubricated with an electrically conducting fluid in the presence of a transverse magnetic field.
Findings
– It is found that the magnetic field effects characterized by the Hartmann number produce an increased value of the load carrying capacity and the response time as compared to the classical Newtonian lubricant case. The modified averaged stochastic Reynolds equation governing the squeeze film pressure is derived.
Research limitations/implications
– The present study has considered both Newtonian fluids and non-Newtonian liquids.
Practical implications
– The work represents a very useful source of information for researchers on the subject of MHD squeeze film with finite porous parallel rectangular plates lubricated with an electrically conducting fluid.
Originality/value
– This paper is relatively original and illustrates the squeeze film characteristics between finite porous parallel rectangular plates with MHD effects.
