The investigation of radiation-absorption

chemical reaction

Hall and ion-slip impacts on unsteady MHD free convective laminar flow of an incompressible viscous

electrically conducting and heat generation/ absorbing fluid enclosed with a semi-infinite porous plate within a rotating frame has been premeditated. The plate is assumed to be moving with a constant velocity in the direction of fluid movement. A uniform transverse magnetic field is applied at right angles to the porous surface

which is absorbing the fluid with a suction velocity changing with time. The non-dimensional governing equations for present investigation are solved analytically making use of two term harmonic and non-harmonic functions. The graphical results of velocity

temperature and concentration distributions on the analytical solutions are displayed and discussed with reference to pertinent parameters. It is found that the velocity profiles decreased with an increasing in Hartmann number

rotation parameter

the Schmidt number

heat source parameter

while it increased due to an increase in permeability parameter

radiation-absorption parameter

Hall

and ion slip parameters. However

the temperature profile is an increasing function of radiation- absorption parameter

whereas an increase in chemical reaction parameter

the Schmidt number

Sc

or frequency of oscillations decrease the temperature profile on cooling. Also

it is found that the concentration profile is decreased with an escalating in the Schmidt number or the chemical reaction parameter.
