An upper layer water inlet well, a lower layer water inlet well and a head endsteady flow wave-absorbing device located on the water outlet sides of the upper layer water inlet well and the lower layer water inlet well are arranged at the head end in a layered flow water tank,and the upper layer water inlet well and the lower layer water inlet well are connected with one end of a head end horizontal partition plate. The tail end in the layered water tank is provided with an upper layer water outlet well, a lower layer water outlet well and a tail end steady flow wave-absorbing device located on the water inlet sides of the upper layer water outlet well and the lower layer water outlet well, and the upper layer water outlet well and the lower layer water outlet well are connected with one end of a tail end horizontal partition plate. The upper layer water inlet wellis connected with the upper layer water outlet well through an upper fluid circulating pipeline system, and the lower layer water inlet well is connected with the lower layer water outlet well through a lower fluid circulating pipeline system.

Description

technical field [0001] The invention relates to a laminar flow physical simulation test water tank system. In particular, it relates to a laminar flow physical simulation test water tank system capable of simulating background flow velocity. Background technique [0002] Fluid stratification is a common natural phenomenon that mainly occurs in oceans, lakes, reservoirs, and estuaries. It is mainly formed by differences in water body density due to differences in temperature, solute content, and sediment content of water bodies at different depths. Stratified flow has an important impact on water conservancy project construction, ecological environment protection, and national production and life. Temperature stratification can inhibit the exchange of water substances and cause deterioration of the water environment; the water quality of lakes, reservoirs and other water sources can directly affect industrial and agricultural production and residents' lives; temperature stra...
