| Abstract: | This investigation examines the time dependent MHD flow problem of a micropolar fluid between two radially stretching sheets.Both the cases(n=0,0.5) of strong and weak concentrations of microelements are taken into account.Suitable transformations were employed for the conversion of partial differential equations into the ordinary differential equations.The solutions of the resulting problems were developed by a homotopy analysis method(HAM).Angular velocity,skin friction coefficient and wall couple stress ... |
| Keywords: | micropolar fluid radial stretching homotopy analysis solution skin friction coefficient wall couple stress coefficient |
