Picture of model of urban architecture

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

The Twisted Delft Hydrofoil and the Potsdam Propeller Test Case (PPTC) were used to analyse and compare the capabilities of Reynolds-Averaged Navier Stokes Equations simulations (RANSE simulations) and detached-eddy simulations (DES) to predict three-dimensional cavitating flow. Although the RANSE simulations were able to predict the lift and drag forces in reasonable agreement with the experiments, it has been shown that the accurate numerical simulation of cavitational flow requires the use of an advanced model such as the SST k-omega detached-eddy model.
