Publisher's Synopsis
This is an overview of the reduction of drag due to passive devices, currently an important technological phenomena. The techniques described point to the reduction of fluid resistance which can result in longer range, reduced fuel costs and higher payload for land, air and sea vehicles, or improved performance of fluids in pipes and channels. The devices covered include riblets and LEBUs, and such additives as dissolved macromolecules, suspended fibres and fine particles.;Practical considerations discussed cover the cost of the techniques and their modelling and construction, their industrial applications, problems caused by their complexity and potential trade-offs or penalties associated with their use.
