Heat transfer enhancement of continues stretching sheet in the existence of radiation due to use of micropolar fluid

A two-dimensional steady convective flow of a micropolar fluid over a stretching sheet in the presence of radiation with constant temperature is studied in this paper. The corresponding momentum, microrotation and energy equations are analytically solved using Homotopy Analysis Method (HAM). To validate the method, investigate the accuracy and convergence of the results, a comparison with existence numerical and experimental results is done for several cases. Finally, by using obtained analytical solution, for the skinfriction coefficient and the local Nusselt number as wellas the temperature, velocity and angular velocity profiles are obtained for different values of the constant parameters, such as Prandtl number, material, boundary and radiation parameters
