Magnetic fluid lubrication of porous pivoted slider bearing with slip and squeeze velocity

Abstract

In this paper the problem on “Magnetic fluid lubrication of porous-pivoted slider bearing with slip velocity by N Ahmad <em>et</em>.<em>al</em>.[7]" has been recapitulated using Jenkin's model [4] with the additional effect of squeeze velocity of the above plate. It is found that while discussing the above problem, [7] has stated but ignored the term , where +, in their study (Refer equation(2.2)). This paper reconsiders the above neglected term with , where . Since is the corotational derivative of magnetization vector, so it has an impact on the performance of the problem [9]. With the addition of the above term and under an oblique magnetic field, it is found that the dimensionless load carrying capacity can be improved substantially with and without squeeze effect. The paper also studied in detail about the effects of squeeze velocity and sliding velocity. It is observed that dimensionless load carrying capacity increases when squeeze velocity increases and sliding velocity decreases.
