dc.description.abstractIn this paper, a theoretical study on the effects of MHD and surface roughness on the couple stresses squeeze film lubrication between circular stepped plates is presented. The modified averaged Reynolds equation is derived on the basis of Christensen's stochastic theory for rough surfaces. The closed form expressions are obtained for the mean squeeze film pressure, load carrying capacity and squeeze film time. The results are presented for different operating parameters. It is observed that the effect of applied magnetic field on the squeeze film lubrication between circular stepped plates with couple stress fluids is to increase the load carrying capacity significantly and to delay the time of approach as compared to the corresponding non-magnetic case. © 2012 Elsevier Ltd.
