Steady Reynolds-averaged Navier-Stokes equations were solved through a finite volume technique, whereas roughness was modeled with experimentally determined roughness functions. First, the methodology was validated with previous experimental studies with a flat plate. Second, flow around the Kriso Container Ship was examined. Lastly, full-scale results were predicted using Granville's similarity law. Results indicated that roughness has a similar effect on the viscous pressure resistance and frictional resistance around a Reynolds number of 10(7). Moreover, the increase in frictional resistance due to roughness was calculated to be approximately 3%-5% at the ship scale depending on the paint.eninfo:eu-repo/semantics/closedAccessAntifouling paintSurface roughnessFrictional resistanceShip resistanceComputational fluid dynamicsRANSArticle191415210.1007/s11804-020-00130-wN/AWOS:0005486907000042-s2.0-85086849681Q2
