The Performance Analysis of a Magnetic Fluid-Based Hydrodynamic Long Journal Bearing

摘要

An attempt has been made to investigate the performance characteristics of a hydrodynamic long journal bearing taking recourse to a magnetic fluid lubricant. With the usual assumptions of hydromagnetic concern Reynold's equation for the fluid film pressure is solved with Sommerfeld boundary conditions. This leads to the calculation of load carrying capacity. The results are presented graphically. It is found that the pressure is marginally affected by clearance ratio. It is noticed that the bearing system records an enhanced performance owing to magnetic fluid lubricant. Undoubtedly, the eccentricity ratio plays a performance role in the augmented performance. In addition, there appears to be less possibility of cavitation due to magnetic fluid lubricant.
