Forced convection multifunctional liquid medium experimental loop

Abstract

The invention discloses a forced convection multifunctional liquid medium experimental loop which mainly comprises a storage tank, a power pump, a valve, a flow meter, an experimental section, a medium pipeline, a purifying system, a heating system, a heat insulation system and the like. The power pump is utilized as a power source for driving a liquid medium to flow; the flow meter measures the flow rate of the liquid medium in the device in real time; the valve controls the flow direction and the flowing or static state of the medium in the device; the flow rate of the medium in the loop is controlled in multiple positions by virtue of a bypass valve and the power pump as well as the flow meter; and after the experiment is over, all the media are collected in the storage tank by depending on the elevation angle of the pipeline and the gravity action of the liquid medium. A plurality of circuit branches and experimental section junctions in the loop can be combined, the required experimental sections can be extended according to specific experimental requirements, and corresponding experimental environment (such as a temperature field, a stress field, a magnetic field, a flow field and the like) can be constructed in the loop of the liquid medium. The forced convection multi-functional liquid medium experimental loop can be widely applied to the fields of industrial application and scientific research projects for developing relevant researches on key technical problems.
