Experimental device for detachable multifunctional bent river channel water circulating system

Abstract

The invention provides a detachable multifunctional bent river channel water circulating system. The bent water circulating system consists of a support structure, a water pump, a 90-degree bent segment, a bent channel segments, a direct channel segment, an energy dissipation grating, a water tank, a telescopic pipeline segment and a measuring device, wherein the bent channel segments are riveted. The system has the advantages of simple structure, high operability, easiness for detaching and carrying and wide research application. The detachable multifunctional bent river channel water circulating system is used for researching the water flow characteristics, sediment movement characteristic and interaction characteristic of flow and sediment in direct channels and bent channels, and has great meaning on the experimental researches of hydraulics, river dynamics direction and sediment dynamics direction.

Description

technical field [0001] The invention relates to a hydraulic engineering experimental device, in particular to an experimental device for a curved river water circulation system. Background technique [0002] The meandering river is the most common river form in nature, and the study of the dynamic process of the meandering river has both important theoretical value and great practical value. Model experiment is a basic method to study bend water flow. Although there have been many achievements in the existing research on water flow in bends, most of them are for simple bends. However, the water flow structure, sediment movement law and river bed deformation law of the fully developed continuous bend with multiple river bends still need to be further studied. Existing experimental research is basically limited to the core area of ​​the water flow in the bend water flow, and there are few studies on the turbulent flow characteristics near the water surface and the side wall,...

AI Technical Summary

Problems solved by technology

Existing experimental research is basically limited to the core area of ​​the water flow in the bend water flow, and there are few studies on the turbulent flow characteristics near the water surface and the side wall, which is difficult to be used for the overall verification and theoretical analysis of the mathematical model

In addition, many current bend water circulation system experiments draw water from underground reservoirs, which occupy a large area and have little flexibility.
