AbstractA survey of literature relevant to drag reduction using grooved surfaces is presented. It was found that, for external air flows, longitudinal grooves were capable of reducing drag when their heights and spacings expressed in terms of the law-of-the-wall coordinates as h+ and S+ were less than 25 and 100, respectively. Experiments were performed to confirm that, within this range of h+ and S+, drag reduction is also possible for internal turbulent flow of water in grooved channels.
