Nusselt number

 

Experiments to determine the local convection heat transfer coefficient for uniform flow normal to a heated circular disk have yielded a radial Nusselt number distribution of the form

where both n and α are positive. The Nusselt number at the stagnation point is correlated in terms of the Reynolds  and Prandtl numbers


Obtain an expression for the average Nusselt number,  corresponding to heat transfer from an isothermal disk. Typically, boundary layer development from a stagnation point yields a decaying convection coefficient with increasing distance from the stagnation point. Provide a plausible explanation for why the opposite trend is observed for the disk.
