Problems solved by technology

Therefore, the boundary tidal method is generally used to generate tidal surge. At present, the method of adjusting the sudden change of the pump flow is used to generate tidal surge at the lower boundary of the tank, but it is greatly affected by the characteristics of the pump power, lift, and response time, and the workload of testing and debugging is large.

Embodiment

[0058] The present invention is a tidal generation method based on a push plate, the moving speed of the push plate is designed based on the surge strength, and the thrust and power on the push plate are designed, figure 1 Generating a schematic diagram for a tidal consists of the following steps:

[0059] S1, determine the relevant parameters of the indoor water tank, including the width, height and bottom slope of the rectangular water tank;

[0060] Determine the width of the trough according to the width of the tide to be formed B . This example takes B =1.0m.

[0061] Based on the maximum swell height that needs to be generated H max , maximum pre-tidal water depth h max0 and super high H c , to determine the height of the sink H w = H max + h max0 + H c , this example takes H max =0.5m, h max0 =0.5m, H c =0.5m. the height of the sink H w =1.5m.

[0062] The bottom slope is 0, which is a flat bottom.

[0063] S2, the moving speed of the push pl...

Abstract

The invention discloses a tidal bore generation method based on a push plate. The method comprises the following steps of S1, determining related parameters of an indoor water tank, wherein the related parameters comprise the width, the height and the bottom slope of the rectangular water tank; s2, the moving speed of a push plate is determined based on the pretidal water depth and the tidal bore height; s3, thrust and power acting on the push plate are determined according to the pre-tidal water depth, the tidal bore height and the moving speed of the push plate; and S4, based on the required power acting on the push plate, the required motor power is designed, and the motor pushes the push plate to generate the tidal bore. According to the method, the generation of the tidal bore in the indoor water tank is designed, and the required tidal bore height can be generated in the indoor water tank. According to the method, the design cost is saved.

Description

technical field [0001] The invention relates to the field of river control engineering, in particular to a method for generating tides in an indoor tide-gushing flume test. Background technique [0002] Tide surge is a special hydrodynamic phenomenon that occurs in strong tidal estuaries. Before and after the surge, there are sudden changes in water level and velocity (flow). After the tide, the water level rose sharply. There are about 450 estuaries in the world with tidal currents, but there are only more than 10 estuaries with value for appreciation. Among them, the Qiantang River and the Amazon River in Brazil are the most spectacular. [0003] The tidal flume test is an important research method to study the hydrodynamic characteristics and propagation law of tidal tidal, as well as to evaluate the interaction between tidal and engineering. Tide generation is the key and difficult point of tidal flume test. The characteristics of flume test require the formation of ti...
