TY - JOUR T1 - Effect of Change in Radial Clearance on Pressure Variation of Fluid in Hydrodynamic Journal Bearing AU - Erhunmwun, İredia AU - Akpobı, John PY - 2019 DA - March Y2 - 2019 DO - 10.22399/ijcesen.492548 JF - International Journal of Computational and Experimental Science and Engineering JO - IJCESEN PB - İskender AKKURT WT - DergiPark SN - 2149-9144 SP - 31 EP - 36 VL - 5 IS - 1 LA - en AB - Thiswork entails the parametric study of the effect of the change in bearing radialclearance with pressure variation of the fluid (lubricant) in a hydrodynamic journalbearing was carried out. The classical Reynolds Equation was used to representthe pressure behaviour in the bearing. This study was carried out using theGalerkin Finite Element Method (GFEM). The result obtained shows that thepressure increases from the ambient pressure which is taken to be zero andincreases significantly till 145.37370. At this point, the pressureis maximum with 1.955 MPa and then drop until it gets to 1800 wherethe pressure equals the ambient pressure. Between angular displacements of 1800and 3600 there were also pressure variations which were equal inmagnitude with those between 00 and 3600 but withdifferent direction. From the foregoing, it is observed that as the radialclearance increases, the pressure in the bearing drops significantly.Therefore, in the design of journal bearings, the radial clearance should ahigh as possible to reduce the pressure in the bearing. The result obtainedshows a strong positive correlation with existing result in literature.
