In this second paper, the influence of inlet pressure boundary conditions on the static characteristics of sector-shaped pad thrust bearings, which are subjected to the effects of both turbulence and fluid inertia forces, is investigated theoretically and experimentally. The basic lubrication equations presented in the first paper are solved by a numerical technique combining the control volume integration and the Newton-Raphson iteration method under the three kinds of inlet boundary conditions in accordance with three types of lubrication conditions. The theoretical results pertaining to the pressure distribution, load carrying capacity and center of pressure are obtained for θ=60°, R_1=0.5, A=1.0-2.0, Re=2 000 and R^*_e=0-1.6, and the results of the load carrying capacity are compared with the experimental results. From these theoretical and experimental results, the relationships between the inlet boundary conditions and the static characteristics of sector-shaped pad turbulent thrust bearings are clarified.
