Mechanical vs. phenomenological formulations to determine mean aerodynamic drag from stereo-PIV wake measurements

Abstract: The present work compares two different drag breakdown methods based on the wake survey of a finite size wing. The traditionnal control volume approach based on a global balance of momentum (cf. for instance [17]) is considered, and compared to the phenomenological drag breakdown formulation put forward by Méheut & Bailly [14] within the aerodynamic context. Both formulations require information on the velocity field, but also the static or stagnation pressure in the wake plane of the model of interest. In thi… Show more

“…The preliminary results shown here are promising, and suggest that stereo-PIV may indeed be a pertinent option when determining all far-field drag components acting on a model, within an industrial context [65]. First, the dramatic time savings introduced by this method makes it viable to measure a large number of samples.…”
