Description

Technical field

[0001] The invention relates to the technical field of reactor thermal hydraulics and safety, in particular to a reactor thermal hydraulic simulation test device and a fluid dynamic characteristic simulation method. Background technique

[0002] In the existing large-scale nuclear power plants or nuclear power plants, the scale of various thermal systems is huge, and it is difficult to carry out tests by means of full-scale simulation. Therefore, a system simulation test device that scales the prototype according to certain simulation criteria is often used to study the thermal and hydraulic characteristics of the reactor system. Commonly used simulation criteria include geometrical similarity criteria, dynamics similarity criteria, and related dimensionless criteria. The application of dynamics similarity criteria must ensure that the simulation test device is consistent with the fluid dynamics of the prototype. Since the simulation test device is different from...
