| Abstract: | The gravity fed system in the space environment simulator is discussed in this paper. The working principle and the process of fluid flowing in shroud pipes are analyzed. The design method of the shroud in the gravity fed system is proposed with theoretical formulas and the design process. The curves of the diameter and the heat load of branch pipes against the volumetric void fraction are obtained for shroud designing. |

| Keywords: | gravity fed system two-phase flow void fraction thermal shroud branch pipe |
