摘要：

This paper presents a steady-state numerical study of a zero boil-off liquid hydrogen storage tank in microgravity conditions. An injection configuration including a nozzle head and a guide tube is equipped to the ZBO tank. The colder liquid hydrogen injected from the nozzles and the guide tube cools down and mixes the main heated fluid inside the tank. The heated fluid then is driven from the outlet opening towards the external cooling system including a pump, cryocooler and heat exchanger to be cooled down and pumped into the injection configuration again to complete a working cycle. An axisymmetric model is employed to analyze the fluid flow and heat transfer inside the storage tank. Twenty five cases selected by the L
