A Study of Hydromagnetic Longitudinal Rough Circular Step Bearing

Abstract EN

This article discusses the effect of longitudinal roughness on the performance of hydromagnetic squeeze film in circular step bearing.

To characterize the random roughness of the bearing surfaces the stochastic model of Christensen and Tonder has been employed.

The stochastically averaged Reynolds’ type equation is solved using suitable boundary conditions to obtain the pressure distribution and then the load bearing capacity is computed.

The results are presented in graphical form.

The graphical results presented here establish that the hydromagnetic lubrication offers significant help to the longitudinal roughness pattern to enhance the performance of the bearing system.

Of course, conductivities of the plates, standard deviation, and the supply pressure contribute towards reducing the negative effect induced by variance (+ve) and skewness (+ve).
