Thesis title
Investigating the impact of mutual sheltering of roughness elements on the drag partition over surfaces
Research overview
Accurate predictions of drag over surfaces remains an important issue faced by engineers. The complex interactions between the surface and the flow, which dictates the operational performance of vehicles, remains inadequately understood when surface roughness is involved. Surface roughness is a prevalent problem and is particularly detrimental for shipping, where biofouling (the settlement of marine organisms on to the hull of the vessel) has enormous financial and environmental consequences. We are striving towards enhancing our predictive capability by systemically probing the effect of different physical measures of roughness. This work is complemented by detailed investigations of flow sheltering, whereby the contribution of roughness to drag depends on wake interactions with nearby surface features.
