Abstract
A new method is described for thermodynamic calculations of a two-phase thermosyphon loop based on a one-dimensional finite element division, where each time-step is split up in a change of enthalpy and a change in entropy. The method enables the investigation of process responses for a cooling loop from room temperature down to cryogenic temperatures. Simulated process responses are compared to a two-phasae deuterium and a two-phase hydrogen thermosyphon loop. The comparisons show that the method can be used to optimize the design of such loops with respect to performance and resulting void fractions.Citation
