A numerical investigation on the effect of different paint coatings on ship resistance in real sailing conditions

In recent years, experimental investigations have been performed on the effect on drag foul release coatings at the University of Newcastle in partnership with International Paint Ltd.

The effect of surface roughness on the skin friction of flat surfaces was investigated in Newcastle's cavitation tunnel, and the effect of biofilm (slime) was tested in the flow cell. This research allowed a step change in the understanding of the effect of different surface finishes on skin friction. However, limitations due to the experimental nature of the tests led to some critical research questions remaining unanswered. The project aims at developing an in-depth understanding on the effect of different different roughness heights and roughness distributions on the boundary layer of merchant vessels at at high Reynolds numbers (10^9).
