Laboratory methods of measuring the wall-friction and micro-geometry of an irregularly rough surface are described. These methods have been used, for the case of a simulated ship-hull roughness, in an attempt to quantify the total flat-plate wall-friction coefficient at full-scale Reynolds numbers and to investigate the consequences of painting the surface in terms of both the wall-friction and surface micro-geometry.
