Abstract
This paper aims to analyze the effect of transverse surface roughness on the performance of squeeze film in parallel circular disks with non-Newtonian ferrofluid under the presence of transverse magnetic field. The modified Reynolds’ equation obtained by applying the Shliomis ferrohydrodynamic model incorporating the Stokes micro-continuum theory, has been stochastically averaged taking recourse to Christensen and Tonder’s model for transverse roughness. With the aid of suitable boundary conditions the equation has been solved to derive the expression for the pressure distribution, thus resulting in the calculation of load carrying capacity. The results establish that the transverse surface roughness significantly affects the squeeze film performance. This article offers some measures to compensate the adverse effect of roughness under suitable conditions due to the positive effect of non-Newtonian ferrofluid.
