Increased urbanization, climate change and overloading of the existing sewer system contribute to the rising risk of flooding in the UK. The consequences of flooding can have severe implications to the social, economic and environmental wellbeing of a community, making effective stormwater management an essential part of any new construction project. Stormwater runoff is often managed using Vortex Flow Controls (VFCs), which restrict the flow of water leaving the site during heavy rainfall events by inducing a vortex in the flow. This study discusses the application of OpenFOAM to characterize the performance of VFCs across all operating modes and compares the simulations with results from full scale physical testing. The numerical results were used to compliment a parametric experimental study and to determine VFC performance outside the limits of what could be tested experimentally.
