概要

• 論文の詳細を見る

• As a sequel to the previous report of this series, the author has this time taken up the fin-edge as one component surface composing a fin array and experimentally studied natural convection heat transfer from the fin-edges in air. The effect of fin geometry and temperature on the respective heat transfer coefficients for the upper, vertical, and lower edges of fin arrays has been clarified. Furthermore, empirical formulas for the respective average Nusselt numbers are obtained. It is found that the heat transfer coefficients for the lower and vertical edges show fairly high values, e.g. 20〜30kcal/m^2hr℃.
