Magnetohydrodynamic effects on finite and infinite slider bearings
Hassan II University of Casablanca, Faculty of Sciences and Techniques PO Box 146, 20650 Mohammedia, Morocco
This paper presents a numerical investigation of lubricating slider bearings with conducting couple stress fluids using externally applied magnetics fields. The modified two-dimensional magnetohydrodynamic couple stress Reynolds-type equation is obtained. This governing equation is resolved numerically by using finite diﬀerence scheme, which involves the Gauss–Seidel method to compute the bearing characteristics. Numerical results using different considered values of the couple stress and Hartman number are presented. These results demonstrate that the transverse magnetic field and couple stress effects are significant.
