dc.description.abstractA potentially powerful influence on the dynamic characteristics of a journal bearing is the thermal deformation of the bearing surface and the journal. Although a few reported research projects consider this effect, most of the journal bearing codes currently utilized in the turbomachinery industry ignore this influence. A study of the thermohydrodynamic behavior including thermoelastic deformation of a two axial groove journal bearing is presented in this thesis. The finite element method has been used to solve the governing differential equations. Quadrilateral nine noded isoparametric elements are used in the finite element model of both the fluid film and the bearing liner. The analytical predictions are compared with the steady load data obtained from two identical 101 mm dia, 57 nm long bearings, one fabricated from steel and the other from bronze. The comparisons are made for several loading values and for operational speeds of 1000 and 5000 RPM (16.66 Hz and 83.33 Hz). Analytical results are also presented for an operating speed of 10000 RPM (166.66 Hz).en
