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