Abstract
A review of riblets as a smart flow control device is given. After the state-of-the-art examination of the drag reduction performance, different views on the drag reduction mechanism are put in perspective. Being a smart flow control device, riblets can control not only momentum, but also heat and flow noise. Some of the available results are summarized to encourage the readers to consider other applications of riblets. Although useful for research investigations, riblets films are not industrially friendly. Here, recent efforts in manufacturing the micro-groove surfacein situare reviewed, including an overview of patents relating to the production of riblets.
