An Investigative Study Of Gurney Flaps On A Naca 0036 Airfoil, Gregory F. Altmann
An Investigative Study Of Gurney Flaps On A Naca 0036 Airfoil, Gregory F. Altmann
Master's Theses
This project examined the effect of Gurney flaps on a 2D, 2-ft chord NACA 0036 airfoil in the Cal Poly 3’x4’ low speed wind tunnel at 25 m/s. It also covered the numerical simulation of the experiment in computational fluid dynamics (CFD). During the study, problems with the wind tunnel data were seen. After a careful diagnosis, the problem was traced to dirty flow conditioners which were subsequently replaced.
Five Gurney flaps at 1, 2, 3, 4, and 5% of the chord were tested. The Gurney flaps had the effect of eliminating the lift reversal effect and lowering the profile …
