The effects of chemical reaction,hall,and ion-slip currents on MHD micropolar fluid flow with thermal diffusivity using a novel numerical technique

The problem of magnetomicropolar fluid flow,heat,and mass transfer with suction through a porous medium is numerically analyzed. the problem was studied under the effects of chemical reaction,hall,ion-slip currents,and variable thermal diffusivity. the governing fundamental conservation equations of mass,momentum,angular momentum,energy,and concentration are converted into a system of nonlinear ordinary differential equations by means of similarity transformation. the resulting system of coupled nonlinear ordinary differential equations is the then solved using a fairly new technique known as the successive linearization method together with the chebyshev collocation method. a parametric study illustrating the influence of the magnetic strength,hall and ion-slip currents,eckert number,chemical reaction and permeability on the nusselt and sherwood numbers,skin friction coefficients,velocities,temperature,and concentration was carried out. copyright © 2012 s. s. motsa and s. shateyi.
