Specifically, the skin friction reduction device constituted of either one or two thick rectangular plates. The chord-to-thickness of a plate is 3, and the value of the Reynolds number based on the plate's chord is constant and equal to 1C)4. The problem is numerically treated by the resolution of Navier-Stokes equations for a laminar unsteady flow using a finite volume technique [1]. 1.
