NACA0012 Data as a function of Re for a VAWT model
I need reliable NACA0012 lift and drag data as a function of both Re and angle of attack for use in a double multiple streamtube VAWT model in the range 1e4 < Re < 1e6. I have a Sandia report that has experimental data for Reynolds numbers 1e4, 2e4, 4e4, 8e4, 16e4, 36e4, 7e5 and 1e6. Should I just interpolate these numbers or is there a more accurate method? Should I for example use XFOIL to get the data for finer intervals? Which method would yield best results?
Also, what is the preferred airfoil to use with a Darrieus-type VAWT? I chose NACA0012 based only on the fact that that's the only profile I have at least some data. Should a cambered or perhaps some different NACA00XX airfoil be used instead?
