The parameters of engineering interest for the present problem are the local skin-friction coefficient and the local Nusselt number which indicate physically wall shear stress and rate of heat transfer respectively.
Hence the skin-friction coefficient can be written as:
It may be noted that with an increase in K, H and G the Skin-friction increases, while we observe that the Skin-friction coefficient and the Nusselt number decrease as the velocity exponent parameter m decreases.
The quantities of physical interest, namely, the local skin-friction coefficient [Cf.
The validity of the present solutions is examined by comparing the results for the local skin-friction coefficient [[absolute value of f"(0)].
Table 3 presents representative numerical results for the local skin-friction coefficient [[absolute value (0)].

at the plate when [epsilon] = 0.
Table 1 displays the values of the skin-friction coefficient and Nusselt number at the surface for different values of [[theta].
The results are qualitatively similar and show that increasing the thermal conductivity of the fluid leads to an increase in the skin-friction coefficient but a decrease in the Nusselt number.
Simulations show that the increasing the magnetic field intensity leads to a decrease in the skin-friction coefficient as well as in the heat transfer coefficient.
