A study will provide a detailed flow visualization that may lead to a better understanding of the drag-reduction mechanism of dimpled surfaces. It has been proposed that the interaction between dimples creates a pattern of alternating spanwise velocity over the surface, which reduces the strength of hairpin vortices and reduces skin friction.
