Study on Liquid Nitrogen Gravity Circulation Loop for Cryopumps in Large Space Simulator


Abstract—Gravity circulation loop for the cryopumps of the space simulator is introduced, and two phase mathematic model of flow heat transfer is analyzed as well. Based on this model, the liquid nitrogen (LN2) gravity circulation loop including its equipment and layout is designed and has served as LN2 feeding system for cryopumps in one large space… (More)
