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