Abstract

The fluid simulation flow system for the water icing test is provided for solving the technical problem that in the prior art, ice produced in a refrigerator freezing mode is greatly different from ice produced in different water areas in a natural state in the aspects of mechanical properties and the like, stable fluid is provided for icing, and the fluid can be iced in a low-temperature environment; the flow system comprises a fluid flow assembly, the fluid flow assembly comprises a first diffusion section, a corner section, a first stable section, a contraction section, a second stable section, a test section and a second diffusion section which are sequentially connected, a fluid channel allowing fluid to flow through is formed in the fluid flow assembly, a plurality of arc-shaped flow deflectors are arranged in the corner section, and the test section is provided with a contact part. The system has a turning function, is compact in structure and can be used in a laboratory, so that the change state of water in a natural flowing state after heat exchange with air at a contact part can be observed in the laboratory, and the water icing process can be further researched conveniently.

Description

technical field [0001] The invention relates to the technical field of water freezing test devices, in particular to a fluid simulation flow system for a water freezing test. Background technique [0002] Since the base of the offshore wind power system will freeze during operation, since the ice will affect the power generation of the wind power system, it is necessary to use an icebreaker or artificial heating to melt the ice to eliminate the adverse effect of ice on the wind turbine. In order to eliminate these ices, it is necessary to know the mechanical properties of ice in advance, such as shear force, viscosity, density, etc., and design the force power of the icebreaker according to these parameters. In addition, in scientific research, it is also necessary to observe the freezing process, because different types of ice have different growth processes, and the physical properties of the frozen ice are also different. Observe the growth process of ice to further under...
