Heat and Mass Transfer in Cylindrical Porous Medium of Activated Carbon and Ammonia

In the framework of research in the thermal cooling machines of adsorption, we have developed a model of heat and mass transfer in porous medium of activated carbon reacting by adsorption with ammonia.For the initial conditions and for a given incident heat flux, we compute in every point and at each time the temperature of the porous medium and the adsorbed mass.The validity of the model has been tested with experimental installation simulating an adsorption machine working within a large temperature range (-20 to 250°C) and pressure range (0 to 2.5 106 Pa).
