Abstract

A precise and quantitative experimental analysis of the heat trans- port properties of He II confined to a channel has been performed for Heat flux density and bulk temperature for which the transitions He II — He I, He II — vapor and He II — He I — vapor could occur in the neighborhood of the heating source or in the channel itself. The temperature measurements of the heater and of the He I and He II flow in the channel allow a thermohydrodynamic description of the heat flow. Particular attention is given to the λ transition and thus to the case where a He I layer separates the heater from the He II channel. Moreover, the dynamics of the vaporized He I or He II bubbles is analyzed and their role played in the heat transfer mechanism.
