Description
technical field [0001] The invention belongs to the technical field of reactor simulation, in particular to a method for using a high-temperature and high-pressure water-gas fluid effect simulation device. Background technique [0002] Nuclear power and nuclear power plants mostly use pressurized water reactors. The heat transfer efficiency, heat transfer stability, and steam flow rate and state of the water circuit in the pressurized water reactor are crucial to the heat exchange of the reactor. The related water circuit thermal hydraulics Research is an essential work for the construction of nuclear energy facilities and is of great significance to the development of nuclear energy. Because it is difficult to conduct experiments on a full-scale reactor system, the prototype system is usually scaled down and modeled, and an experimental bench is built to conduct extensive thermal-hydraulic simulation research on the reactor system. For the study of the mutual influence of ...
