The invention relates to the technical field of fluid mechanics experiment devices, and provides a circulating water tank experiment device capable of realizing solution saturation controllability. The device comprises a first power unit, a first transmission unit is connected with the first power unit, a second power unit is connected with the first transmission unit, a second transmission unit is connected with the second power unit, an observation unit is arranged on the second transmission unit, a special-shaped section is connected with the observation unit close to the side of the first power unit, and a rectification section is connected with the observation unit away from the side of the special-shaped section; the first transmission unit and the second transmission unit form a closed circulating water tank enabling a solution to flow stably, the target requirement for airtightness is met, the special-shaped section facilitates transition of an incoming flow field in a second gradual change pipe and later transformation, the rectification section achieves the effect of adjusting the flow field, the observation unit is suitable for observation of the flow field and observation of a test model; and by means of a PIV technology, detailed information such as the flow field streaming phenomenon in the closed circulating water tank is captured and measured through the observation unit.
Description
technical field [0001] The invention relates to the technical field of fluid mechanics experimental devices, in particular to a circulating water tank experimental device for realizing controllable solution saturation. Background technique [0002] Under the condition of specific temperature and pressure, the dissolution of solute in a certain amount of solvent has reached the maximum and cannot be dissolved any more. The solution obtained in this way is called saturated solution. The solution formed before the dissolved amount of solute reaches the maximum is called an unsaturated solution. When the concentration of the solute in the solution has exceeded the solubility of the solute under the temperature and pressure, but the solute has not yet precipitated, it becomes a supersaturated solution. It is a relatively common experiment to prepare gas solutions with different saturations. It is mainly to pass a certain volume of gas into the solution to fully dissolve the gas ...
