The aim is that the experimental device and the experimental method can carry out experiments on water flow characteristics of different types of river channel intersection ports, and are characterized by being easy to operate and being high in reutilization. The technical scheme is that the experimental device suitable for researching water flow characteristics of multiple types of river channel interaction ports is characterized by comprising a Y-shape symmetric river channel intersection experiment unit, two straight river channel interaction experiment units, a bending river channel and straight river channel intersection experiment unit, a water supplying pool set, and an external tank. The experimental method utilizing the experimental device for researching water flow characteristics of multiple types of river channel intersection ports includes the following steps: step 1, determining an experiment zone of intersection of three types of river channels; and step 2, conducting research on many issues through the structure of the external tank.

Description

technical field [0001] The invention relates to the field of hydraulic experiments, in particular to an experimental device and an experimental method for researching flow characteristics of multi-type river intersections. Background technique [0002] The confluence of water flows widely exists in natural rivers and artificial water systems, ranging from the confluence of rivers to the confluence of ditches. The main and tributary rivers meet to form a waterway network, and the water flow at the estuary is difficult to predict. Many large and medium-sized cities are located near the intersection, and the estuary is a key part of the development of water transportation. When converging with tidal currents, the water flow characteristics at the confluence are more complex, so the confluence estuary is also a difficult part of waterway regulation; converging water flow also has a strong retention effect on the transport of pollutants. Therefore, as a key part connecting river...

Problems solved by technology

[0004] (1) Limited by the site, only a single type of intersection can be studied in the experimental tank;

[0005] (2) Existing experimental tanks generally have their length, width and height dimensions fixed. To explore the flow characteristics of converging tanks with different width ratios, the original tank needs to be modified and constructed, which will cost more time and cost ;

[0006] (3) The intersection can involve many issues such as water flow characteristics, sediment movement laws, pollutant transmission and diffusion, runoff and tidal superposition, and the influence of river nodes on water flow characteristics. research content needs
