Difficulties related to the implementation of a one-dimensional test device investigating the heat and mass transfer in a non saturated porous medium.

Summary

The article aims at studying precisely the heat and mass transfer in porous non saturated media or in phase change materials. The authors present a test device with a classical geometry (small diameter cylinder relative to the height with temperatures imposed at the bottom and at the top, laterally isolated), allowing a gammametric measurement of the absorption as a function of the height. The main difficulty depends on the lateral isolation which has to be as efficient in the transient as in the steady state. The main originality is the measurement of the heat flux at the bottom and at the top of the cylinder, thus allowing the thermal insulation to be tested particularly in steady state. The authors present the difficulties related to the development together with the results obtained.
