STUDY ON THERMAL STORAGE IN NON-SATURATED SOILS
The efficiency of energy storage in a saturated layer is linked to a great extent to the energy and matter losses through the non-saturated layer of soil lying above the saturated layer used as a storage zone. In order to study this problem we constructed a physical model of sufficiently large size. A test programme has made it possible to simulate heat storage at 60 degrees C. The surface of the soil was subjected to controlled conditions and then natural atmospheric conditions. The physical model serves as a prototype for the study of the behaviour of a natural site. The evolutions of the physical model make it possible to judge the modifications in the state of the non-saturated layer of soil and to come to conclusions regarding the harmful effects of storage. The physical model has given experimental results that confirm the validity of a local three-phase mathematical model. This confirmation allows this model to be used in the future for making forecasts for other sites.
