Small experimental circulating water tank

Abstract

The invention relates to a small experimental circulating water tank which comprises a water tank body, and the water tank body comprises a test section (1), an upper expansion section (17), a power section (15), a connecting section (12), a third-stage guide section (11), a lower expansion section (10), a second-stage guide section (7), a first-stage guide section (5), a rectification section (4)and a contraction section (3) which are connected in sequence to form a loop, wherein the the test section (1) is horizontally arranged, the first-stage guide section (5), the second-stage guide section (7) and the third-stage guide section (11) are arranged at corners, a honeycomb rectifier (401) is arranged in the rectification section (4), and a plurality of flow deflectors (6) are arranged inthe first-stage guide section (5), the second-stage guide section (7) and the third-stage guide section (11). Compared with the prior art, the experimental requirements can be met, the flow field speed is adjustable, flowing is uniform and stable, the flow velocity distribution of the test section is uniform, and advection and turbulence can be controlled.

Description

technical field [0001] The invention belongs to the field of fluid mechanics research, and in particular relates to a small experimental circulating water tank. Background technique [0002] With the development of modern science and technology, research and problem solving based on fluid mechanics knowledge are required in ocean engineering, fishery production, hydraulic machinery, etc., and the analysis of fluid mechanics experiments is needed in the basic research of fluid mechanics. In order to reduce the experimental cost and obtain more accurate experimental data, experimental research can be carried out in wind tunnels, drag pools, water tunnels or circulating water tanks through similar theoretical analysis. [0003] Most of the water tanks currently used are straight water tanks in static water tanks or dynamic water tanks, and most of them are open, and the shape and size are large, occupying a large space, which cannot make the water flow circulate, and will also ...

AI Technical Summary

Problems solved by technology

This patent has the following disadvantages: (1) the top of the test section cannot be closed, and there are few flow field experiments; (2) the material is PVC material, which has poorer light transmission than plexiglass material; the designed water tank is not easy to clean, It is easy to accumulate sediment inside the tank and affect the flow of the flow field
