Modeling of a vertical circulation open loop in two-phase helium

摘要: An efficient cooling method for superconducting coils of large magnets working at an operating around 4.2 K is a two-phase circulation loop where the flow naturally driven by weight difference between two branches due to vaporization. It has advantage eliminate use pressurization system such as pumps which require costly maintenance and operation these temperatures. To study thermo-hydraulics properties method, single tube experimental test apparatus been built several studies have achieved on heat transfer, pressure drop behavior. assist design system, predictive numerical model developed, in this paper we present modeling configuration comparison with results.
