Zusammenfassung:A numerical experiment is conducted whose results demonstrate the considerable extent to which the highly viscous effects associated with low Reynolds number flows influence subsonic compressibility corrections. The Kothari and Anderson (1985) compressible Navier-Stokes code is used to calculate the flow over a Wortmann FX 63-137 airfoil at freestream Mach numbers of 0.5, 0.4, and 0.3. The highly viscous effects yield a relatively constant center-of-lift up to Mach 0.5. (O.C.)
