چکیده

A free convective unsteady visco-elastic flow through porous medium bounded by an infinite vertical porous plate with variable suction, constant heat flux under the influence of transverse uniform magnetic field along with permeability in the presence of radiation and chemical reaction has been investigated in the present study. The suction velocity of the porous medium fluctuates with time about the constant mean. Approximate solutions for mean velocity, transient velocity, mean temperature and transient temperature, mean concentration and concentration of non-Newtonian flow are obtained. The effects of various parameters such as Pr (Prandtl number), Gr (Grashof number), M (Hartmann number), ω (frequency parameter) and k0 (permeability parameter) and F (radiation parameter) and KC (chemical reaction parameter) on the above are depicted. Expressions for fluctuating parts of velocity ‘Mr’ and ‘Mi’ are found and plotted graphically and effects of different parameters on them are discussed. Skin friction amplitude and phase are shown with the help of figures and are discussed in detail.
