A Study on the Performance of Hydromagnetic Squeeze Film between Two Conducting Truncated Conical Plates

We make an effort to analyze the behavior of hydromagnetic squeeze film between two conducting porous truncated conical plates. The plates are considered electrically conducting and the clearance space between them is filled by an electrically conducting lubricant. A uniform transverse magnetic field is applied between the plates. An attempt has been made to solve the associated Reynolds’ equation with appropriate boundary conditions to obtain the pressure distribution which in turn, is used to get the expression for load carrying capacity which is then used to calculate the response time. The results are presented graphically as well as in tabular form. The results suggest that the bearing system registers an enhanced performance as compared to that of a bearing system working with a conventional lubricant. Further, it is seen that aspect ratio tends to increase the load carrying capacity substantially. It is observed that the combined effect of the semi-vertical angle and the magnetization parameter is relatively better than that of the combined effect of the aspect ratio and porosity. Besides, the conductivity increases the load carrying capacity significantly. The analysis incorporated in this paper presents ample scope for improving the performance of the bearing system considerably by choosing a suitable combination of magnetization parameter, the aspect ratio, semi-vertical angle and the conductivities of the plates.
