Problems solved by technology

The horizontal circulating water tank sets the working section and its power system at the same height, and the power system drives the water flow to circulate at the same height. The general horizontal circulating water tank includes shrinkage section, stabilization section, diffusion section and other parts, which occupy a large area The problem
The general vertical circulating water tank needs to provide fluid potential energy to make the fluid achieve a three-dimensional circulating flow, so the power demand required for the vertical circulating water tank is greater than that of the horizontal circulating water tank. The larger power makes the water flow in the vertical circulating water tank The degree of turbulence caused by entering the reservoir is high, the process required for the water flow to stabilize before entering the test section is long, and there is also the problem that the test device occupies a large area

Embodiment 1

[0032] Such as figure 1 , figure 2 As shown, the present embodiment provides a combined device for circulating water tanks, including a water storage tank 10 and a test section 20 arranged above the outlet of the water storage tank 10, the water storage tank 10 is provided with an array of water inlets 30, the The array of water inlets 30 is used to make the water flow into the reservoir 10 maintain a uniform distribution of speed in the horizontal direction; the reservoir 10 is also provided with a drainage baffle assembly 40, and the drainage baffle assembly 40 is used to make the water flow into the reservoir 10 The water flow in the pool 10 enters the test section 20 after being fast and stable, and the overall flow in the test section 20 is uniform in level and vertically controllable.

[0033] Further, the drainage baffle assembly 40 includes an inlet baffle 41 and a partition baffle 42, and the inlet baffle 41 is arranged in front of the array water inlet 30 to block ...

Embodiment 2

[0043] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 lies in that this embodiment provides a circulating water tank combination device, the partition baffle 42 is a curved stopper structure, and the concave surface of the curved stopper faces downward.

[0044] In order to prove that the flow field with specific characteristics can be formed by using different drainage baffle assemblies 40, the present invention compares such Figure 5 The vortex surface of the flow field of the three flow guide plate assembly conditions shown, the results are as follows Figure 6 shown, from Figure 6 We can find that the tubular vortex generated at the corner connecting the reservoir 10 and the test section 20 using the circulating water tank with a plane stopper and a curved stopper is smaller, and the vortex generated by the curved surface module is the smallest. The vortex can reflect the turbulence of the water flow. Generally speaking, the smaller...

Abstract

The invention discloses a circulating water tank combination device and a water circulation method thereof. The circulating water tank combination device includes a reservoir and a test section arranged above an outlet of the reservoir. An array water inlet is arranged in the reservoir. The array water inlet is used to make a water flow speed of entering into the reservoir be uniformly distributedin a horizontal direction. A drainage baffle plate component is arranged in the reservoir, and the drainage baffle plate component is used for making the water flow which enters into the reservoir berapid and stable and then enter into the test section. Compared with the prior art, the device and the method have advantages that the circulating water tank combination device adopts the drainage baffle plate component so as to shorten a flow path required for water flow stability and save a land occupation area of a test device; the array water inlet is adopted to maintain the uniform distribution of the water flow speed in the horizontal direction so as to achieve a strong water tank flow field adjustment effect with less cost; and the water flow circulation method is used to simplify thetest device, make test water be recyclable and save resources effectively.

Description

technical field [0001] The present invention relates to the technical field of circulating water tanks, and more particularly, to a combined device of circulating water tanks and a water circulation method thereof. Background technique [0002] With the development of modern science, there are more and more achievements not only in the research topics of resistance, propulsion, maneuverability and seaworthiness of ship engineering, but also in ocean engineering, fishery production, hydrology, hydraulic machinery and sports science. More and more fluid mechanics problems need to be studied and solved. These problems can be performed in wind tunnels, drag pools, water tunnels, or circulating tanks as long as similar theoretical requirements are met. [0003] The circulating water tank is a hydrodynamic test equipment that keeps the model fixed, the water flow circulates in the water tank, and ensures that the water flow in the working section is uniform. In the circulating w...
