Open Access research that is exploring the innovative potential of sustainable design solutions in architecture and urban planning...

Strathprints makes available scholarly Open Access content by researchers in the Department of Architecture based within the Faculty of Engineering.

Research activity at Architecture explores a wide variety of significant research areas within architecture and the built environment. Among these is the better exploitation of innovative construction technologies and ICT to optimise 'total building performance', as well as reduce waste and environmental impact. Sustainable architectural and urban design is an important component of this. To this end, the Cluster for Research in Design and Sustainability (CRiDS) focuses its research energies towards developing resilient responses to the social, environmental and economic challenges associated with urbanism and cities, in both the developed and developing world.

Abstract

Model tests were carried out in a towing tank to investigate the effects of helical grooves on the drag loading of stationary circular cylinders in uniform and steady currents. A series of models were made and tested, including smooth and rough cylinders with and without grooves. The maximum Reynolds number achieved in the tests was about 4x10(5). The comparative results between the smooth and grooved cylinders show that the helical grooves reduce the drag loading by between 18 and 25% depending upon the cylinder surface roughness and the Reynolds number. This is a continuation of our work published in OMAE06 in Hamburg on VIV suppression by the use of helical grooves.
