Inertia effects in the flow of a simple casson fluid between two fixed surfaces of revolution

Answer 1

Many fluids with microstructure demonstrate viscoplastic behaviours. Rheological measurements indicate that flows of these fluids may be modelled as flows of the Casson fluid. Our concern in the paper was to examine the pressurized flow of a simple Casson fluid in a thin clearance between two fixed surfaces of revolution. In order to solve this problem, the boundary layer equations were used. The effects of inertia forces on pressure distribution are examined by using the method of averaged inertia. Numerical examples of externally pressurized flows in the clearance between parallel disks and concentric spherical surfaces are presented.
