✦ Synopsis

The analysis of a He II transfer process consisting of a fountain effect pump coupled to a transfer line is presented. It is shown that the flow rate of the fountain effect pump is largely determined by the hydraulic load, i.e. the transfer line. Based on the isocaloric equation for ideal superfluid flow, pump performance curves are developed. The pressure drop along the transfer line is modelled by using expressions for turbulent flow. Performance of the pump and transfer line are coupled to provide a complete system for analysis. Results are formulated in terms of the hydrodynamic impedance of the system. Examples are studied using the characteristics of the SHOOT transfer line.

The thermomechanical flow of He II through a porous element for a fountain effect pump was experimentally investigated to understand the general flow characteristics in both ideal and turbulent flow states. The flow rate increases in proportion to the heat input Q in the ideal superfluid flow state
