This paper includes:
- an experimental study on the kinetic of formation of magnetite and hydrogen released on mild steel with a free or pre-oxidized surface. The conditions to elaborate water-steel heat pipes are described.
- a study on the behaviour of Toluene, Naphtalene and Quinoline heat pipes submitted to transient conditions and heated by means of a gazeous thermal flow. The flooding data measurements agree well with the Prenger's correlation.
