Title :層流境界層の遷移過程における伝熱機構の研究(第1報)
Title alternative :A study of the Heat-transfer Mechanism on the Transition (1st Rep)

Abstract :The transition from Laminar to turbulent flow were made by two-dimensional roughness element (cylindrical) affached to the flat plate. The experiments were made on the boundary layer along a flat plate in a two-dimensional wind tunnel. The purpose of this experiments is to make the fundamental data, and discuss the effect of the ratio of its roughness element diameter K to the displacement thickness δ^* on the local value of the heat transfer coefficients in the transition region. When k/δ^* is large. large Value of the heat transfer coefficient is obtained at the place affached the element, and its Value is larger than that of the turbulent flow in a flat plate
