“…[30] was developed a model with the effective dispersion coefficient as a function of flow velocity. Bart et al [5] presented solutions for non-isothermal adsorption with maldistribution in fixed-bed for small changes of temperature and constant overall transport coefficient, Mhimid [31] provides calculations for desorption.…”

“…The heat transfer between air flow and the zeolite beads was calculated with Dittus and Boelter's equation, cf. [150,151]. The sorption isotherm and the water uptakedependent differential heat of adsorption were fitted empirically by a polynomial approximation to the corresponding experimental data, respectively.…”

“…Several 1D or 2D energy storage models based on adsorbent materials such as zeolites can be found in the literature [12,13,14,15,16]. To predict the spatiotemporal behaviour of the storage system during heat charging and discharging, a two-dimensional model taking the specificities of cementitious material into account was developed.…”

Renewable energy storage is now essential to enhance the energy performance of buildings and to reduce their environmental impact. Most adsorbent materials are capable of storing heat, in a large range of temperature. Ettringite, the main product of the hydration of sulfoaluminate binders, has the advantage of high energy storage density at low temperature, around 60°C. The objective of this study is, first, to predict the behaviour of the ettringite based material in a thermochemical reactor during the heat storage process, by heat storage modelling, and then to perform experimental validation by tests on a prototype. A model based on the energy and mass balance in the cementitious material was developed and simulated in MatLab software, and was able to predict the spatiotemporal behaviour of the storage system. This helped to build a thermochemical reactor prototype for heat storage tests in both the charging and discharging phases. Thus experimental tests validated the numerical model and served as proof of concept.
