The characteristic of forced convection heat transfer over a inclined flat plate of finite width with a semi-circular nose is investigated by the experiments in the range of the attack angle of incidence α= -20〜20°, the finite width w = 30〜110mm (its aspect ratio of width to thickness w/2h=3〜11) and the unit Reynolds number U_∞/v_∞ =5.5×10^5 〜1.1 ×10^6m^-<1> (μ_∞ and ν_∞ : velocity and kinematic viscosity of free stream). At the front surface of W/2h≧6, when α<5°the local heat transfer coefficient remains almost in the value for α=0°,but it reduces remarkably to above decreases to a certain extent with a decrease of μ∞.At the back surface, the heat transfer always enhances better as α increase. The local heat transfer plates of W/2h<6, the heat transfer performance is greater than that of wider plates. The heat transfer characteristic corresponds well to the Flow one.
