Behaviors of Micropolar Flows in a Rotating Annulus Available to Purchase

An analysis is presented for the problem of micropolar flows in the annulus between two steadily rotating concentric cylinders. The local effects arising from microstructure and intrinsic motion of the fluid element that will affect the flow motion are considered. Especially, the effects of non-zero values of micro-gyration vector on the wall boundary conditions are investigated, using micropolar fluid theory. Numerical results of velocity distribution of micropolar fluids are compared with the corresponding flow problems for a Newtonian fluid. Also, the results of the surface friction coefficient and the couple stress coefficient at the inner and outer surfaces are prepared with various values of fluid properties and flow conditions.
