Environmentally Sustainable Shipping Through Improved Understanding and Management of Wall-Bounded Turbulence.

Grant number: FT110100432 | Funding period: 2012 - 2016

Abstract

The thin region of turbulent flow that is pulled along by a ship's hull as it moves through the water accounts for up to 90 per cent of the overall resistance and a large amount of the fuel burnt. This project aims to control or tame recurrent flow patterns within these turbulent regions to reduce resistance, overall fuel cost and emissions from shipping.
