Drag and Noise Measurements on an Underwater Vehicle with a Riblet Surface Coating

Abstract

From 50 to 80 percent of the energy by marine vehicles (ships, submarines, torpedoes, etc.) is used solely to overcome turbulent skin drag. It is not surprising, therefore, that both government and industry have invested heavily in research focused on the problem of turbulent skin friction. Of the many approaches to reduction of turbulent skin drag, the recently introduce riblet concept is among those that show the greatest promise for application to existing hull forms. Keywords: Skin drag; Boundary layer; Buoyant vehicle; Riblets, Reprints. (JHD)
