Description

Technical Field

[0002] The morphology of the liquid film, such as its thickness and motion state, and the system pressure drop will affect the performance of the liquid film during use. For example, the thickness of the liquid film will affect the specific surface area and thermal resistance of heat transfer, and the motion state of the liquid film will affect the stability and heat transfer efficiency. The system pressure drop of the liquid film is the pressure drop caused by the energy loss during the flow of the fluid, which will affect the liquid holding capacity and mass transfer efficiency. Therefore, it is necessary to observe the morphology of the liquid film and the system pressure drop during the process. For example, CN105203545B discloses a system and method for observing the morphology of the liquid film in an unfavorable high overload spray cooling test under an unfavorable high overload environment. By observing the thickness of the liquid film on the cooling surface and the formation process and flow morphology of the liquid film after the droplets hit the wall, the pressure source and waste liquid recovery part of the spray cooling system are improved to have anti-overload ability, ensure stable working fluid flow under overload environment, and complete spray cooling and waste liquid recovery. In order to meet the high overload environment in this technical solution, it is necessary to set up components such as motors, rotating arms and counterweights, which makes the equipment area in the system too large, complicated to operate during use, and difficult to maintain.
