A Hydromagnetic Boundary Layer Micropolar Fluid over a Stretching Surface in a Non- Darcian Medium with Permeability

摘要

Hydromagnetic boundary layer micropolar fluid flow over a stretching surface embedded in a non-Dacian medium with variable permeability was considered in this work. The governing partial differential equations were transformed into their equivalent cylindrical coordinate system from its original form (rectangular form). A set of similarity parameters are employed to convert the governing partial differential equations to ordinary differential equations. The obtained self-similar equations are solved using the Adomian Decomposition Method. The effect of various physical parameters on the velocity profile, microrotation and temperature distribution were investigated. The obtained results shows that as the magnetic parameter and the inverse Darcy number D~(-1) increase the velocity profile and the microrotation reduce while the temperature profile increases.
