A Deep Tunnel Storm Water System is built in Dubaï as part of an expanded infrastructure network. The designer commissioned Artelia for a hydraulic scale modelling study of the Terminal Pumping Station in order to validate its hydraulic design and to ensure its proper operation.
The Terminal Pumping Station is responsible for conveying the stormwater runoff into the sea during nominal flow.
3D numerical drawing of the pumping stationAims of the physical scale model
The objective of this model is to ensure the proper functioning of the Terminal Pumping Station by checking the following criteria :
submerged and free surface vortices,
pre-rotation in pump suction,
non-uniform distribution of the velocity at impeller eye,
entrained air or gas bubbles,
inflow conditions from the outlet of the tunnel,
distribution of the flow across the wet wells.
Description of the physical scale model
The physical model represents all the relevant geometry of the Terminal Pumping Station : the main inlet tunnel, the three screens chambers, the two wet wells for the four pumps, the anti-vortex devices.
The model is also equipped with measurement devices : electromagnetic flow meter, swirl meter and Pitot tubes.
