Inertia effects in thrust curvilinear hydrostatic bearing lubricated by a Casson fluid

Many lubricants demonstrate non-Newtonian behaviours. Rheological measurements indicate that the flows of these lubricants may by modeled as the flows of a Casson fluid. In this paper theoretical aspects of hydrodynamic lubricantion of a curvilinear thrust bearing lubricated by a Casson fluid are considered. The effects of inertia forces on the pressure distribution are examined by using the method of averaged inertia. As examples step and spherical bearings are discussed.
