• The experiments are carried out using a flat plate which is partly heated under constant heat flux conditions. The plate is submerged in air and water flows. With the measured wall temperature distributions known, heat flux is calculated by employing the Rubesin's or the Seban's heat transfer cofficient and by the method of superimpositions of temperatures. As the result, it is known that the Prandtl number effect on the coefficient is close to P_r^<1/3>. However, sufficient accuracies of the calculation are still not obtained even by employing the Rubesin's formula which includes P_r^<1/3> in it. The author proposes and develops a method in this report to utilize the Spalding function for the calculation of the superimposition. The experimental results prove that the proposed method is more accurate than the former.
