MIXED CONVECTION BOUNDARY-LAYER FLOW OF A MICROPOLAR FLUID NEAR A STAGNATION POINT ON A HORIZONTAL CYLINDER

The theory of micropolar fluids due to Eringen is used to formulate a set of boundary layer equations for the mixed convective flow of an incompressible micropolar fluid in the vicinity of the front stagnation point on an isothermal circular cylinder. The governing conservation equations have been solved numerically. Missing values of the velocity, angular velocity and thermal functions are tabulated for a wide range of the material parameters of the fluid, the buoyancy parameter and the Prandtl number of the fluid. Micropolar fluids display drag reduction and reduced surface heat transfer rate as compared with Newtonian fluids. © 1990.
