| Abstract: | Special constraints are imposed on liquid helium transfer in space relying on the fountain effect (thermomechanical effect) for the movement of liquid He II below the lambda point. The present Paper considers thermodynamic pump system options and compares performance figures with requirements of different system selections. |
