“…Simulation studies of functioning of the storm water drainage with accompanying facilities, such as storm water overflows [19,48], separators and reservoirs are becoming essential tools for use in engineering practice [32,35,36]. In recent years, many studies have focused on the assessment of the reliability and risks associated with the functioning of urban infrastructure systems [5,14,22,42,43,50], as well as the impact of changes climate for their functioning [16,21,23,25,28,29,37,41].…”

“…In this regime there is a free surface flow and the flow through the outlet orifice is largely similar to flow over a thin plate weir. The behaviour of a VFC in the vortex flow regime has been investigated previously, albeit not extensively (Deamer, 1988;Green, 1988;Parsian and Butler, 1993;Priestman, 1987;Wojtowicz and Kotowski, 2009). Much less work has been done to investigate the flow at low flow rates -in fact, it is the authors' belief that the current work is the first attempt to analyse thoroughly this regime computationally.…”

A vortex flow control with differing outlet shapes is investigated computationally at low flow rates. The volume of fluid method was utilised to track the moving free surface. In order to achieve a smooth free surface, interface compression coupled with the inter-gamma compressive scheme was used. The turbulent evolution of the two-phase flow was modelled by solving the Reynolds-averaged Navier-Stokes equations with the k-å model for turbulent quantities. Validation of the results was carried out by analysing the total head and discharge coefficient for the three outlet shapes at various flow rates and comparing these results with experimental data. Very good agreement with the experimental data was obtained.

Abstract. Vortex flow regulators (VFR) are used in urban drainage systems as a replacement for traditional flow throttling devices. Vortex regulators are not only very efficient energy dissipators but also atomizers which are beneficial for sewer aeration. A deficit of dissolved oxygen can be a problem in both natural waters and sewerage. Hydrodynamic flow regulators can boost oxygen concentration preventing putrefaction and improving treatment of stormwater and wastewater. We were first to investigate the aeration efficiency of semi-commercial scale cylindrical vortex flow regulators to determine the potential of their application in environmental engineering and to propose modification to enhance the aeration capacity of basic designs. Different device geometries and arrangements of active outlets for both single and double discharge vortex regulators were tested in a recirculating system. In this study, we present a concise review of the current state of our extensive research on the aeration efficiency of vortex flow regulators and their application in sewerage systems.
