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=10^4, 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.
