Abstract: This research was carried out to make clear the surface heat transfer in the starting range of parallel plates. The laminar heat transfer in the range was theoretically analysed and compared with the experimental results, and the turbulent heat transfer was made clear by various experiments. In the theoretical analysis, the distributions of both velocity and temperature were approximated by the biquadratic equations and the solutions were obtained taking into consideration the fact that the velocity of the main stream accelerates as the boundary layer from the walls grow. Regarding the velocity boundary layer, the results of this solution agree well with that of the Schlichting's exact analysis. Moreover, the theoretical result of the laminar heat transfer agrees also with the experimental results. The experiments were carried out in the passage of parallel plates having flat front edges, and the influences of velocity and the breadth of passage on the length of the starting range and heat transfer were made clear. As the result, it is found that the heat transfer in this case is considerably close to that of the case of a single plate, especially in the range of turbulent boundary layer.
