Abstract

We compare the accuracy achievable with different methods of calculating time-averaged airfoil loads if the surrounding velocity field is known, e. g. , from Particle Image Velocimetry. These methods require integration over a control volume enclosing the body. For separated flow around an inclined flat plate at Re = 104, we investigate the effect of varying the control volume. Some methods yield excellent results for both lift and drag. Preliminary results for a corresponding experiment indicate that the calculated lift coincides well with direct force measurements, whereas agreement for the drag can be considered fair. Implementation of the methods was validated using a circular cylinder flow at Re = 200.
