EGA324: Aerofoil Experiment - Swansea University - Mechanical Engineering

Internal Code: MAS6891

Mechanical Engineering:

Questions: 1) Are there any appreciable fluctuations in either the recorded pressures or velocities? 2)Is there any reason to doubt the accuracy of the measured lift and forces? 3) Can you include a measure of error bars on your experimental data? 4) Describe the shape of the pressure distributions over the aerofoil using Bernoulli’s equation 5)Explain your results – what happens to the flow over the aerofoil as it approaches and goes beyond the stall angle? How are the pressure and velocity connected along a streamline? 6) Were you able to obtain previous data for comparison at a similar Reynolds number and for the same foil (NACA0012). If not, how do your results compare to the measured results in the reference given to you 7) What is the influence of the Reynolds number on the peak lift and drag? 8) What is the influence of the AoA on the pressure distributions? 9) At what angle of attack did the stall occur, and how was this affected by the Reynolds number? 10)How does the data compare to any published experimental data? 11)How does it compare to theory or empirical equations?
