THE SURFACE ROUGHNESS AND TURBULENT WALL FRICTION ON SHIP-HULLS. INTERACTION IN THE VISCOUS SUBLAYER

Measurements of the roughness function for several ship-hulls with varying surface roughness are shown and the lack of any observable pattern with respect to the roughness height, as a sole correlating parameter, is pointed out. A practical criterion is developed for a turbulent boundary layer on a rough flat plate with zero pressure gradient. Order from NSFI as No. 17430.
