  1. ( 3 ) using conformal mapping, the longitudinal protrusion height and the lateral protrusion height on the v - grooved surfaces are given, on this basis, some drag reducing features in parallel - flow, cross - flow and enlarge - flow are presented and analyzed ; in addition, drag reducing features with blade - shaped grooves and u - shaped grooves are discussed, consequently, the riblets designing criterions are suggested which will reduce the drag and noise most effectively underwater
