Abstract
An investigation has been launched in to the performance of a rough porous parabolic slider bearing under the presence of a magnetic fluid lubricant. The bearing surfaces are assumed to be transversely rough and this random roughness of the bearing surfaces has been characterized by a random variable with non-zero mean, variance and skewness. The concerned stochastically averaged Reynold’s equation is solved with appropriate boundary conditions to obtain the pressure distribution resulting in the calculation of load carrying capacity. Further, the friction, the position of centre of pressure and temperature rise has been calculated. The results show that the effect of magnetization characterized by the magnetization parameter induces an improvement in the steady state performance as compared to the traditional conventional lubricant case, in spite of the fact that the transverse roughness adversely affects the bearing system. Further, a comparison of this investigation with the case of plane inclined slider bearing indicates that the magnetization results in a higher load carrying capacity and reduced friction. Also, the negatively skewed roughness and variance (-ve) enhance the already increased load carrying capacity due to magnetization.
