The flow of a Herschel-Bulkley fluid in a curvilinear thrust hydrostatic bearing is considered. The bearing is modeled by two curvilinear surfaces with common axis of symmetry. The flow in the bearing clearance is considered with inertia effect. Using the averaged inertia method the closed-form solution to the equations of motion is obtained. A step bearing is discussed as an example.
