Question 1: Determine the boundary layer thickness d and boundary layer displacement thickness d* along the wind tunnel walls at the trailing edge of the wing. Assume that the wing is installed in the test section with the leading edge 3 ft from the start of the test section segment. Use tunnel and wing geometry data provided previously. Assume the test section velocity found in Part 3 of the project for a power input of 80 hp.
Question 2: Determine the full scale Reynolds number, assuming sea level properties for air provided previously. Assuming transition occurs at a Reynolds number of 500,000, where will transition occur on the full scale wing? Where should it occur on the model if Reynolds number is matched?
Question 3: At model scale, if we are to consider a minimum height h/c of 0.125, what percentage of this height will be occupied by the wing and tunnel wall boundary layers?
