Abstract


In this paper, an analytical solution for the performance characteristicsof squeeze film lubrication between rough conical plates with Rabinowitsch fluid has been studied. The modified Reynolds equation has been inferred on the basis of Christensen’s stochastic model for rough surfaces.Two sorts of one-dimensional roughness patterns, viz. radial and azimuthal roughness are considered. Utilizing a small perturbation method, a closed-form result is obtained. Expressions are obtained for pressure, load carrying capacity and squeeze film time. For different operating parameter, the outcomes have been calculated. It is seen that the influence of radial(azimuthal) surface roughness pattern is to increase (decrease) the pressure, load carrying capacity and squeeze film time.
