AB A mixture of water and naphthalene was used as working fluid for a two-phase closed thermosyphon in order to study the behavior during the operation of such device working with an immiscible mixture. A small proportion of water was used and tests using a glass tube were initially made to visualize the phenomenon. A metallic tube was constructed to observe the temperature profile under higher values of heat
input. The experiments showed that the naphthalene concentrates in the lower part of the tube while the water
occupies the upper part at the end of the condenser. There is a temperature difference between these two
sections, with a significant drop in the transition from naphthalene to water. The latter condenses on the wall
surface and evaporates as the drop crosses the interface. The system works as two thermosyphons connected in
series. The analysis of the interface position shows that an increase on the power supplied to the system leads to
an advance of the interface towards the top of the thermosyphon.
