โœฆ Synopsis


The efficiency of a pumping system is defined in terms of energy flows into and out of a control volume surrounding the pump. It is shown that the centrifugal pump power requirement is affected little by the heat leaks expected in a planned He II transfer system. In contrast, the power requirement for a superfluid fountain effect pump is greatly dependent on the thermal conduction through both the porous plug and the downstream transfer line. If the downstream conduction is negligible, the efficiency of a fountain effect pump will be significantly less than that of available centrifugal pump&

Turbulent He II flow behaviour in superfilters of non-cylindrical shape at large temperature gradients was investigated. It was found that the mass flow rates were always lower than those that would follow from a straightforward extrapolation of results obtained at small temperature gradients; under

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
