The flow of a couple-stress lubricant in a clearance of a curvilinear thrust hydrostatic bearing with impermeable walls is considered. The flow in the bearing clearance is considered with inertia forces. The equations of motion are solved by an averaged inertia method. As a result, the formulae for pressure distributions without and with inertia effects were obtained. Radial thrust bearings and spherical...
Many electrorheological fluids (ERFs) as fluids with micro-structure demonstrate a non-Newtonian behaviour. Rheometric measurements indicate that some flows of these fluids may by modelled as the flows of a Vočadlo ER fluid. In this paper, the flow of a Vočadlo fluid – with a fractional index of non-linearity – in a narrow gap between two fixed surfaces of revolution with a common axis of symmetry...
Many electrorheological fluids (ERFs) as fluids with micro-structure demonstrate viscoplastic behaviours. Rheological measurements indicate that the flows of these fluids may be modelled as the flows of a Casson fluid. Our concern in the paper is to examine the pressurized laminar flow of an ERF of a Casson type in a narrow clearance between to fixed surfaces of revolution. In order to solve this...
Many electrorheological fluids (ERFs) as fluids with micro-structure demonstrate viscoplastic behaviours. Rheological measurements indicate that the flows of these fluids may be modelled as the flows of a Bingham fluid. Our concern in the paper is to examine the pressurized laminar flow of an ERF of a Bingham type in a narrow clearance between to fixed surfaces of revolution. In order to solve this...
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...
