Experimental Investigation of the Flowfield around a Multielement Airfoil.

Kurzfassung

Detailed measurements on mean flow and turbulence around a multielement airfoil model have been made using pressure and hot-wire probes. The results obtained in two test cases at chord Reynolds number of 3 x 10 exponent 6 and freestream Mach number of 0.2 show a number of features of the complex flows that are important for accurately modeling these flows by numerical methods. Many parts of the shear flow deviated vastly from classical flows, and the interaction with the external flow is very strong.
