POLLUTANTS’ CONCENTRATION INFLUENCE ON THE SHAPE OF AVERAGED TWO-PHASE FLOW VELOCITY DIAGRAM
Preliminary results of experimental studies on the phenomenon of changing the shape of the diagrams of averaged velocity at the inlet and outlet of the devices for pre-treatment of surface runoﬀ from coarse impurities are given. The comparison of laboratory results with the results of measurements made in the reservoirs in the drainage area of the old city in Paris proves the possibility of studying this phenomenon using the physical model. More extensive research in this area can improve the existing mathematical model of the two-phase flows in water drainage systems.
