The flow and heat transfer characteristics of forced convection over an inclined flat plate finite width, having a plate width of w=80 mm and plate thickness of 2h=10 mm, are investigated. Emphasis is placed on those in the region near the leading edge, where the separation bubble and the side edge vortices strongly interact. In order to vary the interaction quality, three leading noses of a semicircle, triangle (apex of 90°) and rectangle are used. The experiments are performed in the range of the attack angle of incidence, α=-20°~+20°, under the condition of the unit Reynolds number, U_∞/v_∞=1.1×10^6 m^<-1> and of the heat flux, q=1500 W/m^2. The local heat transfer characteristic depends considerably on the shapes of the leading edge and the attack angles of incidence. However, in the range of α>15°, the dependence becomes undistinguished.
