Résumé

This paper describes the creation and validation of a computer model of a liquid helium transfer line located at the Canadian Light Source (CLS) in Saskatoon, Canada. This line transfers liquid helium to a cryostat, which contains a superconducting radio frequency (RF) cavity, and requires precise pressure and level modulation to ensure proper RF control. A detailed mathematical model of the transfer line is created based on mass, momentum, and energy continuity along with pressure-volume-temperature relations. The model is discretized and solved, and model results are compared with experimental data taken from the actual cryostat at the CLS to validate of the simulation. The validated model is found to reasonably predict flow rates through the transfer line at the CLS from a process perspective.
