Abstract
Inspired by the dolphin skin, compliant coatings have been researched as a passive flow control solution to reduce drag. Both successful and drag-increasing experiments can be found in the literature. However, the mechanism is not well understood neither the combination of surface properties and flow conditions that yield a drag reduction. At Dimple Aerospace, the aim was to find the optimal space of coating properties and flow conditions that yield a drag reduction. To this end, a series of compliant coatings with varying stiffness have been drag-tested. On the softer coatings that altered the flow back, the surface deformation is characterised by the FS-SS technique. Finally, PIV is performed to observe the effect of the coating deformation in the flow.
