Experiments have been conducted on three geometrically similar air-foils. Since airfoils are thin, the fluid flow over airfoils can be considered to be like flow over flat plate, i.e., the streamwise pressure drop can be neglected. airfoils width of The (perpendicular to air stream) is 1.0 m. Neglect the curvature of airfoils in your calculations. The results obtained from experiments are shown below: Length, L (m) 1 0.2 0.5 Velocity, U.. (m/s) 10 5 10 Air temp., T.. Airfoil No. (K) 300 1 2 300 3 300 Considering the results presented in the above table, answer the following questions: Airfoil temp., Ts (K) 320 320 320 - We know that C = C Rem in which Cf and Re, are the average friction coefficient and the Reynolds number, respectively. Moreover, C and m are two constant parameters. Find C and m. Determine the friction on airfoil No 3 Determine the heat transfer between Airfoil 1 and the air stream Thermophysical properties of air is constant in all experiments. p= 1 kg.m k = 0.05 W.m-1.
