The temperature distribution within the thermal boundary layer over a heated isothermal flat plate is given by \(\frac{{T - {T_w}}}{{{T_\infty } - {T_w}}} = \frac{3}{2}\left( {\frac{y}{{{\delta _t}}}} \right) - \frac{1}{2}{\left( {\frac{y}{{{\delta _t}}}} \right)^2}\), when Tw and T∞ are the temperatures of plate and free stream respectively, and y is the normal distance measured from the plate. The local Nusselt number based on the thermal boundary layer thickness δt is given by
