Abstract

This paper aims to investigate the effects of rotational inertia force on the squeeze film characteristics between two circular disks lubricated with a non-Newtonian ferrofluid. Based on the Shliomis ferromagnetic fluid model incorporating with the Stokes couple stress fluid model, we have derived a non-Newtonian ferromagnetic Reynolds equation including the rotational inertia force effects for the study of squeeze film performances. From the results, the effects of rotational inertia forces of the upper disk yield a lower load capacity and a shorter squeezing time as compared to the non-rotating case. In addition, the influences of the related parameters on the squeeze film characteristics are also included in Table 1 for engineering applications.
