My wind tunnel has following measure: L= 123 cm, b=61cm, H=31cm.
in the attachment the blue curvature ist from xfoil and the red curvature is from my measurement. There is an offset between the both curvature, i don't know why. I read in book that to match them i need to correct my measured...
some reports compare their measured data with simulation data, and they match very well. But before comparaison they brought some correction of their measured data. The problem is that they don't explain very well what they did.
That is why i'searching now for a very example where almost...
i'm a new user of xfoil. I make measurements (Cp) in wind tunnel. But my measured data don't match with the data of xfoil. I use xfoil like my reference.
Which correction can i bring to my measured Cp so that measured and simualation data match together?
Cp = pressure coefficient
thanks...
