Heat transfer characteristic in turbulent flow over a flat plate having finite width is experimentally studied with emphasis on the promotion of heat transfer caused by the edge effect due to the secondary flow at the plate corner. The measurements under the condition of uniform heat flux are performed for the geometries of finite widths w=60〜360 mm and of finite thicknesses 2h=10〜40 mm. The relatively great promotion of heat transfer is always obtained at the side edge region of finite width and it depends mainly on plate thickness. The local heat transfer coefficient in the lateral direction is well expressed by the empirical formulae of Eqs. (3)〜(6) with plate thickness as a parameter. The formulae for the mean heat transfer coefficients are also established by the set of Eqs. (7)〜(10).
