Abstract
This paper deals with a theoretical analysis on the effect of viscosity variation on a ferrofluid based long bearing. The model of Tipei considering viscosity variation is deployed here. The magnetic fluid flow is governed by Neuringer-Rosensweig model. The pressure distribution is obtained after solving the associated Reynolds type equation, which gives the load carrying capacity. The computed results indicate that the increased load carrying capacity owing to magnetization gets negligible help from the effect of viscosity variation.
Highlights
A magnetic fluid is a liquid that is strongly magnetized when an applied magnetic field is present
A number of authors dealt with the effect of magnetic fluid in different types of bearing for instance; Tipei (1982) in short bearing, Agrawal (1986), Shah and Bhat (2003) and Deheri and Patel (2011) in slider bearing, journal bearing by Nada and Osman (2007) and Patel el al. (2012), circular plates by Shah and Bhat (2000), Deheri and Abhangi (2011), Patel and Deheri (2014, 2015), Patel and Deheri (2016) in Annular plates and Parrallel slider bearing by Patel and Deheri (2016)
Studies have been made to deal with the effect of viscosity variation on the performance of a conventional lubricant based bearing system
Summary
A magnetic fluid is a liquid that is strongly magnetized when an applied magnetic field is present. It is a colloid made of nanoscale mono-domain ferromagnetic particles suspended in a carrier fluid (water, oil or other organic solvent). By the application of a suitable magnetic field, the viscosity of the ferrofluid increases leading to the enhanced load carrying capacity (Odenbach, 2003), Chandra et al, 1992). Patel and Deheri (2019) examined the performance of a magnetic fluid based short bearing considering the viscosity variation. It was deliberation suitable to present a study of a theoretical analysis on the effect of viscosity variation on a ferrofluid based long bearing
