In one embodiment, a method for reducing drag includes forming a smooth surface (122) on a first portion (120) of a physical object (100). The method also includes forming periodic riblets (110) on a second portion (130) of the physical object. The second portion of the physical object is adjacent to the first portion of the physical object. Each riblet of the periodic riblets of the second portion of the physical object is depressed below a plane of the smooth surface of the first portion of the physical object. The method further includes generating a flow over the periodic riblets of the second portion of the physical object and over the smooth surface of the first portion of the physical object. A length of each riblet of the periodic riblets runs parallel to a direction of the flow.
