Description
Technical Field
The invention belongs to the technical field of experimental devices, and particularly relates to a villiaumite flowing solidification behavior simulation experiment system.
Background
The molten salt reactor is a reactor used as fluoride coolant in a fourth-generation advanced nuclear energy system, has high energy conversion efficiency, good safety, normal-pressure operation and good nuclear diffusion prevention property, and is a fourth-generation reactor type which is intensively developed by GIF (global institute of nuclear power and energy international forum (nuclear reactor)). Supercooling and freezing of coolant in the flowing process is a difficult problem which must be solved before safety review and commercial operation of the molten salt reactor. Because the melting point of the coolant used by the molten salt reactor is far higher than the ambient temperature, if the coolant is solidified, a series of challenges are brought to the safe operation of the reactor, for example, the heat exchange capacity is reduced due to the reduction of the circulation flow, the flow channel is blocked, even the pipeline is damaged, and the safety of the reactor system is damaged. Therefore, equipment damage or system failure caused by the overcooling solidification of the reactor coolant in the steady-state operation of the reactor or in the later period of an accident is classified as one of design benchmark accidents requiring important attention of the molten salt reactor. Therefore, the research on the fluorine salt solidification behavior experiment is of great significance.
At present, the research of solidification experiments of molten salts under the flowing condition is almost blank, and the research on the solidification mechanism, the heat and mass transfer behaviors in the solidification process and the flowing resistance characteristics is very limited. Due to the high melting point and non-visual characteristics of the molten salt fluid, the experimental study on the flow solidification of the molten salt fluid by using a traditional method is difficult, the existing flow solidification model is obtained based on the flow solidification experiment of unitary fluid such as water and the like or the numerical simulation of binary liquid mixture which is not fully verified, and the applicability and the accuracy of the model to the fluoride coolant used by the molten salt reactor are still to be verified. For liquid mixture coolants used in molten salt piles, there is no fixed solidification point of a unitary fluid like water, but rather a mushy zone comprising a liquid phase and a solid phase is created during solidification, the solidification mechanism of which is clearly distinguished from that of a unitary fluid. Therefore, advanced experimental measurement methods are necessary to carry out deep research on the flow heat and mass transfer mechanism of the material. The operating temperature of the fluorine salt is too high, the melting point is higher than 400 ℃, the high-temperature fluorine salt has strong corrosion to the pipeline, the difficulty of carrying out the fluorine salt experiment is high, and the cost is high.
The thermodynamic behavior of Dowtherm A or Drakesol260AT produced by Dow chemical company in the lower temperature range is very similar to that of high temperature FLiBe, and the characteristic makes Dowtherm A or Drakesol260AT feasible for simulating high temperature fluorine salt under low temperature conditions.

The pressure in the heat conduction oil storage tank is controlled by a pressure controller and a pressure relief valve which are arranged above the heat conduction oil storage tank. The flow of the heat conduction oil in the experimental section is realized by adjusting different pressure differences between the two heat conduction oil storage tanks, so that the change range of the Reynolds number of the heat conduction oil is 20-10000. Considering that the experiment section can be solidified, the front flow and the rear flow of the experiment section can be changed, and therefore, two flowmeters can be respectively arranged at two ends of the experiment section and used for measuring the flow of the inflow experiment section and the outflow experiment section.

The reason for the rectangular channel design is to facilitate optical observation and study of the solidification behavior of the fluid on the plate. Visual measurements include simultaneous measurements of Particle Image Velocimetry (PIV) and Laser Induced Fluorescence (LIF).

Meanwhile, rhodamine B solution with the concentration of 0.2mg/L is added as fluorescent particles. In order to realize the synchronous measurement of the PIV and the LIF, a spectroscope is used for dividing the light path of the experimental section into a PIV light path for measuring the speed field of the experimental section and an LIF light path for measuring the temperature field of the experimental section.

In order to reduce the length of a laminar flow or turbulent flow development area of the solidification experiment section, the end parts of the solidification experiment section on two sides are provided with buffer cavities 53, two opposite side surfaces of each buffer cavity 53 are provided with openings 53A as inlets of heat conduction oil, the heat conduction oil of the solidification experiment section enters from two sides of the buffer cavities, is mixed to enter the buffer cavities, and then flows out from the side surfaces of the buffer cavities to enter the solidification experiment section. In order to further enhance the buffering effect of the buffer cavity, the cross-sectional area of the buffer cavity along the fluid flowing direction can be set to be larger than that of the solidification experimental section, the heat conduction oil in the buffer cavity can enter the direction and flow out of the heat conduction oil on the same straight line, and the heat conduction oil can enter the direction and flow out of the heat conduction oil to be vertical or in other suitable modes.
Further, the loop of the freezing section is arranged to be symmetrical about the experimental section. The advantage of symmetry lies in can accomplishing once experimental back, need not return the conduction oil to original conduction oil holding vessel again, but can readjust the pressure differential of two conduction oil holding vessels, makes the conduction oil flow direction reverse, carries out next operating mode experiment to improve test efficiency.
