Problems and Development of Methods of Dynamic Simulation of Cryogenic Systems

Аннотация

The problems of designing and employing cryogenic systems operating in transient modes over a considerable operating time as well as various methods of simulating transient operation of these systems are discussed. The advantages of application of dynamic simulation of cryogenic systems over classical methods of calculation of steady-state mode are shown. The available information on dynamic simulation of large helium cryogenic systems is reviewed. To validate the dynamic simulation method, the transient mode of operation of a large helium liquefier is analyzed applying universal software tool for dynamic simulation modeling of chemical systems, the results of which are compared with the experimental data.
