WebN2 - The stability characteristics of water-lubricated journal bearings having multiple axial grooves are studied theoretically. These bearings can use the process fluid as the lubricant as in the case of feed water pumps. The process fluid (water) is fed from one end of the bearing, through the multiple axial grooves (groove angles may vary). WebThis example compares the load bearing abilities of different hydrodynamic bearings. The simulation is performed using the Rotordynamics Module’s Hydrodynamic Bearing …

Webto as the short bearings and the latter, the long bearings. The approximations lead to the following equations 1 : W= 3 DL 8c2 2 0.62 +11/2 1− 2 2 for short bearings 1 and W= 3 3D L 4c2 2 4 2+ − 2 1/ 2+ 2 21− for long bearings 2 Equations 1 and 2 may be used as primary anchor expres-sions to develop a load-capacity expression for finite ... WebDiscretized forms of the transformed equations are obtained by the control volume method and solved by the SIMPLE algorithm. Results indicated that when compared with the conventional lubricant, the ferrofluid as a lubricant enhances the hydrodynamic characteristics of journal bearings and provides a higher load capacity. density of water at 22.1 degrees celsius
