Dynamic modeling of a supercritical helium closed loop with the 4C Code

Abstract

A new Modelica library has been developed, which provides the framework for the drag-and-drop cryogenic circuit modeling capability of the Cryogenic Circuit Conductor and Coil (4C) code. The code has been applied to the simulation of a thermal-hydraulic transient in a closed supercritical helium (SHe) loop, driven by a pulsed heat load and including multiple feedback controls. The 4C results are in good qualitative agreement with those of the Vincenta code. © 2012 American Institute of Physics.
