*I. J. Uwanta, **A. Hussaini

Abstract


The purpose of the present work is to study the influence of viscoelastic and mass transfer on unsteady MHD micropolar flow of incompressible and electrically conducting  micropolar fluid past a semi-infinite vertical porous plate in the presence of a transverse magnetic field and periodic suction. Closed form solutions have been obtained for the mean velocity, mean angular velocity, mean temperature and mean concentration using perturbation technique and these are presented in graphical form. The effects of different physical parameters such as magnetic Hartmann number, thermal and solutal Grashof number, Prandtl number, Schmidt number, skin friction, heat transfer coefficient and Sherwood number are presented and discussed.


Keywords


Viscoelastic, Micropolar fluid,porous medium, thermal diffusion,variable suction.
