FLOW AND HEAT-TRANSFER OF A MICROPOLAR FLUID IN AN AXISYMMETRICAL STAGNATION FLOW ON A CYLINDER

An analysis is presented for the steady state boundary layer dow and h eat transfer of a micropolar fluid in the vicinity of an axisymmetric stagnation point on a cylinder. The governing momentum, angular moment um and heat transfer equations have been solved numerically using a pr ocedure based on an expansion of Chebyshev polynomials approximation. Missing values of the velocity, microrotation function and heat transf er are illustrated for a range of values of material parameters and Re ynolds numbers. The results have been compared with the results of the corresponding flow of a Newtonian fluid. It is observed that micropol ar fluids display drag reduction when compared to Newtonian fluids.
