Magneto-Hydrodynamic Squeeze Film Characteristics between a Sphere and a Plane Surface
並列摘要
Based upon the thin-film magneto-hydrodynamic (MHD) theory, this paper analyzes the squeeze-film characteristics between a sphere and plane surface lubricated with an electrically conducting fluid in the presence of a transverse magnetic field. The MHD Reynolds-type equation governing the squeeze-film pressure is derived using the continuity equation and the magneto-hydrodynamic motion equations. A closed-form solution for the squeezing film pressure is obtained, and applied to predict the MHD squeeze-film characteristics. According to the results obtained, the presence of externally applied magnetic fields signifies an enhancement in the squeeze-film pressure. On the whole, the magnetic-field effects characterized by the Hartmann number produce an increase in value of the load-carrying capacity and the response time as compared to the classical Newtonian-lubricant case. It improves the squeeze film characteristics of the sphere-plane surface system.
