Abstract
A recent trend in industry is to use directly lubricated bearings with reduced oil flow to achieve minimum power consumption. However, too much oil flow reduction would cause bearing failure. This work presents a comprehensive thermohydrodynamic algorithm that predicts the performance of the leading-edge groove bearing under low oil flow and starvation conditions. Because of starvation, more analyses are added and extra uncertainties are inevitably introduced in the theoretical models. The influence of starvation on pad temperature, power loss, journal eccentricity, attitude angle, and dynamic coefficients are investigated and discussed. The numerical results are compared with published experimental data with generally satisfactory agreement.
