Abstract

The invention discloses a small-sized closed horizontal circulating water channel device which is a closed flow circulating channel composed of sections. The top of a test section is open, a bent section of a medium guide section is provided with a medium guide corner rectifier, a bent section of a large guide section is provided with a large guide corner rectifier, and a '#'-shaped cellular rectifier and a net rectifier are arranged between the large guide section and a first contraction section sequentially. A small guide section is provided with a rotary shaft, and the rotary shaft is provided with a propeller at one end. By the structure, the closed horizontal circulating water channel has the advantages that a circulating pipeline flows stably; the water channel is suitable for observation of a flow field and observation of a test model; flow rate of a test section along a cross section is distributed evenly and the speed rate is controllable; speed of advection and speed of turbulence are controllable; and water transparency is high, and a fluid mechanics basic test, a ship maneuverability test, a large-sized algae cultivation method test, observation and shooting of a flowing pattern and the like can be performed.

Description

technical field [0001] The invention relates to a simulation experiment equipment, specifically a simulation experiment equipment for basic theoretical research and application research on fluid mechanics, fishing gear model, navigation model, fish behavior, large seaweed cultivation, artificial fish reef model, etc. circulation tank equipment. Background technique [0002] With the development of modern science, more and more hydrodynamic problems need to be studied and solved in ocean engineering, fishery production, hydrology and hydraulic machinery. As long as the requirements of similar theories are met, these problems can be solved in wind tunnels, Test in towed pools, water holes or circulating tanks. In the past, the straight water tank and the annular water tank in the static water tank or the moving water tank were used, both of which were open. Because the water flow could not circulate stably in the straight water tank, it often brought difficulties to repeated ...
