0] [square root of ([sigma] / [mu])] is the Hartmann number, Gr = [rho]g[beta][R.
In order to see the effects of Hartmann number M on w for [[lambda].
m] is the Grashof number for mass transfer, E is the Eckert number, M is the Hartmann number, P is the Prandtl number, [S.
Figures 1, 2 and 3 exhibit the variation of the velocity field u versus y under the effect of Soret number So, Hartmann number M and Eckert number E.
Here we observe that the retardation due to an increase in the porous parameter is more rapid than that due to increase in the Hartmann number
The figure 1 illustrates the behavior of pressure gradient with increase in stenosis size for different values of Hartmann number
The variation of axial pressure gradient dp/dx with Hartmann number M for [phi] = 0.
It is found that, the pressure gradient and the time averaged flux increases with increasing Hartmann number M, half width of the plug flow region [y.
The parameter A is a thermal influence parameter (see Cramer and Pai ) and M is the Hartmann number.
This is because the variation of the Hartmann number leads to the variation of the Lorentz force due to the magnetic field and the Lorentz force produces resistance to transport phenomena.
1] are respectively the Prandtl number, Grashof number, Sink strength, Eckert number, Hartmann number, co-efficient of thermal diffusivity and non-Newtonian parameter.
r], Hartmann number M, sink strength S, Grashoff number G and Eckert number [E.
