Lifting force for ferrofluid-based oblique pad stator influenced by concentration and film ratio

Abstract

The present article aims to investigate hematite suspension-based inclined slider pads under the impact of polarization forces. The mathematical modelling for pressure and load capacity under an oblique variable magnetic field and squeeze has been carried out using the theory of Shilomis flow of ferrofluids. The optimal film ratio values regarding the inclined slider's bearing capacity are analysed under the above dynamic conditions. The impact of the field strength and rotation of magnetic particles on the load is presented through computed data and plots. The investigation reveals that the lifting force is a function of squeeze, which improves remarkably when the particle concentration is raised but has a minor waning with the field strength. Finally, a technique is developed to determine the utilisation of an oblique pad stator with reference to load for the given conditions and the application area.
