Inertia Effect in Hydromagnetic Slider Bearing

Abstract

A theoretical investigation of inertia effects in an inclined slider bearing with an electrically conducting lubricant in the presence of azimuthal magnetic field is presented. It is shown that the load supporting capacity of bearing is increased for short circuit case if the lubricant inertia effects are taken into account. However, the inertia effect becomes smaller when the strength of magnetic field increases. In open circuit case for Hartmann number M≤4 the load capacity increases due to inertia and for M≥5 the load capacity decreases due to inertia. Further it is seen that the effect of inertia is rather small at Hartmann numbers 4.1, 4.2, 4.2 and 4.4 for Reynolds numbers .01, .1715, .25 and 1.39 respectively.
