Abstract

Using the approximation of short journal bearings, analytical solutions of the magnetohydrodynamic form of Reynold's bearing equation are derived. The basis of the approach are the MHD basic equations. The ordinary hydrodynamic assumptions of lubrication are applied. The flow is assumed to be isothermal. Induced magnetic fields are neglected. The Lorentz force is the only body force acting on the fluid. A constant and uniform magnetic field is applied in circumferential direction. The electric field is oriented in radial direction.
