Supply-drainage integrated stratified flow experiment device

Abstract

The invention discloses a supply-drainage integrated stratified flow experiment device, and belongs to the technical field of teaching aids. The experiment device comprises a tank body (1), a first water storage area (2), a second water storage area (3) and a third water storage area (4), a first water delivery pipe (21) is arranged between the first water storage area (2) and the tank body (1), asecond water delivery pipe (31) is arranged between the second water storage area (3) and the tank body (1), the bottom of the tank body (1) is provided with a water-inlet device and a water drainagedevice, the lower layer of the tank body (1) is provided with a water-spilling area (11), a porous media area (12) containing media is arranged on the water-spilling area (11), and an experiment observation area (13) is arranged on the porous media area (12). According to the supply-drainage integrated stratified flow experiment device, lower stream can stably flow to the inside of the tank body(1), the stratified flow interface is clear, the observation effect is good, the structure is simple, the phenomenon is obvious, and the operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of teaching appliances, and relates to a demonstration experiment device, in particular to a stratified flow experiment device integrating supply and discharge for demonstrating liquid stratified flow. Background technique [0002] Stratified flow mainly refers to the phenomenon that two liquids with different densities that can be mixed will be separated after mixing, and relative motion will occur at the interface. When two liquids move relative to each other at the interface, global mixing will not occur. This kind of water layering phenomenon often occurs in the water flow of nature and actual engineering, such as water bodies in large-volume waters such as oceans, lakes, and reservoirs. The temperature difference formed by sunlight makes the temperature of the upper waters and the lower waters different, which will cause stratified flow; some are due to the different sediment content in the water, such ...
