Problems solved by technology

[0003] The existing high-speed water tunnel has serious cavitation phenomenon. When the object model is placed in the water hole for the object model experiment, the high-speed incoming flow will produce a large number of cavitation in the experimental section, resulting in unstable incoming flow, which will affect the quality of the object model experiment. successfully launch

Embodiment

[0022] A schematic diagram of a multiple nested high-speed experimental water tunnel in this embodiment is as follows figure 1 As shown, it includes a large experimental pool 1, a main water pipe 3, a plurality of control water pipes and a plurality of water pumps; a plurality of control water pipes are sequentially nested outside the main water pipe 3, and gaps are provided between adjacent pipes; The two ends of the main water pipe 3 and each control water pipe are respectively provided with an outlet 10 and an inlet, and each outlet 10 is connected to a different water pump;

[0023] The size of the gap between adjacent tubes is related to the shape of the outlet 10, the diameter of the tube, and the length of the test section during the physical model test, and can be set according to specific experiments.

[0024] In the present invention, the main waterway pipe 3 and a plurality of control waterway pipes are nested, and the outlets 10 of the main waterway pipe 3 and each...

Abstract

The invention relates to a multi-nested type high speed experiment water tunnel. The water tunnel comprises a large experiment water pool, a main water channel pipe, multiple control water channel pipes and multiple water pumps. The control water channel pipes are successively nested in the exterior of the main water channel pipe. A gap is arranged between adjacent pipes. Two ends of the main water channel pipe are equipped with an outlet and an inlet and two ends of each control water channel pipe are equipped with an outlet and an inlet. Outlets are connected with different water pumps. The main water channel pipe and the control water channel pipes are assembled and then immersed into different depths in the large experiment water pool. According to the invention, water is pumped into the water pumps from the outlets, then flows out of water outlets of the water pumps and then is mixed with water in the large experiment water pool, so a self-circulation system is formed; when the water pumps are pumping water, flows in the main water channel pipe and the control water channel pipes can be adjusted respectively, so bubbles generated by high speed flowing of water in the main water channel pipe caused by port effects are removed; and when an object model is arranged in the main water channel pipe for an object model experiment, stable incoming flows can be acquired and an excellent experiment environment is created for the object model experiment.

Description

technical field [0001] The invention relates to the field of hydrodynamic experiment technology research, and more specifically relates to a multi-nested high-speed experimental water tunnel. Background technique [0002] The water tunnel is a kind of equipment for hydrodynamic experiments, which can be used to study phenomena such as boundary layer phenomena, turbulent cavitation and water elasticity, and can also be used to study the force between water flow and experimental objects. Therefore, the construction of water tunnels has high value for hydrodynamic research. [0003] The existing high-speed water tunnel has serious cavitation phenomenon. When the object model is placed in the water hole for the object model experiment, the high-speed incoming flow will produce a large number of cavitation in the experimental section, resulting in unstable incoming flow, which will affect the quality of the object model experiment. successfully launch.
