Flow characteristics of superfluid helium through porous elements of thermomechanical pumps were experimentally studied with special emphasis on the critical heat input which bounds the ideal flow regime and the superfluid turbulent flow regime. The dependence of the critical heat input on the tempe

A forced flow superfluid helium circulation system has been developed. Steady state temperature distribution and transient thermal propagation behaviour along the cooling channel have been investigated. The results are analysed on the basis of the energy equation using the Gorter-Mellink relation. T
