Effect of Surface Roughness on the Behaviour of Ferrofluid Based Squeeze Film Between Porous Annular Discs
Efforts have been made to study and analyse the performance of a ferrofluid based squeeze film between rotating porous transversely rough circular plates. The Neuringer and Rosenweig model for ferrofluid flow has been adopted to get the effect of magnetization. The stochastic model of Christensen and Tonder has been used to evaluate the surface roughness. The stochastically Reynolds` equation is utilized to get expression for pressure distribution which results in calculation of load carrying capacity. The effect of magnetization improves the performance of bearing system by increasing the values of load carrying capacity. The results are presented in graphical, which shows that bearing suffers due to transverse roughness. The combined effect of porosity and aspect ratio enhances the load carrying capacity. The negative mean and negative skewness also advances the attainment of bearing system. Proper value of magnetization parameter and ferrofluid as a lubricant extends the performance of bearing compare to conventional lubricant.
