Abstract
A modified two-fluid model is applied to the present numerical analysis in order to study the flow and heat transfer of superfluid helium in a micro-channel with a diameter as small as that of a Superleak in a Fountain Effect Pump. Variable properties of superfluid helium and energy dissipations due to two-fluid mutual friction and friction at the channel wall are taken into consideration. The calculation results were in good agreement with experimental results; thus, this simulation code can be used for analyzing flow and heat transfer of superfluid helium in a micro-channel.
