- •
A comparison between different LHTS systems is investigated.
- •
A thermal characterization of the PCM and the ENG/PCM composite is performed.

The exchanger using an ENG matrix has the highest heat transfer coefficient.
- •
An enthalpy model is developed for heat transfer simulation in the LHTS.
- •
An identification of the thermal contact resistance is performed.
