SOME FLOW PROBLEMS IN MICROPOLAR FLUIDS

Abstract

In the present paper, we study the flow behaviour of micropolar fluids whose constitutive equation were formulated by Eringen in the conventional simple shearing flow,Couette flow and Poiseuille flow. We note characterstics features of these fluids, like micro-rotation, unequal shearing stresses and couple streses in each of the cases. We also compare the flow behaviour of the above fluids with those which occur in the case of Don-Newtonian fluiids characterised by other ,well-known constitutive equations.
