- Outcome of the Energy Technology Partnership-funded project 'Compliant coatings for tidal turbine blades'. Reports Direct Numerical Simulations of turbulent channel flows at low and intermediate Reynolds numbers. Shows that large-scale passive streamwise wall fluctuations can reduce friction drag, whereas even small passive spanwise wall fluctuations lead to considerable drag penalty. Informs the development of practical active and passive control strategies for turbulent friction drag reduction. Collaboration between the University of Aberdeen, University of Edinburgh, and International Paint Ltd. (contact: Barry Kidd , Section Manager, Marine R&D).
