SC 99-04 Frank Seewald, Anja Pollei, Matthias Kraume, Walter Mittelbach, Jens Lang.: Numerical Calculation of the Heat Transfer in an Adsorption
Energy Storage with KARDOS
Abstract: A new seasonal energy storage for thermal solar systems
has been
developed on the basis of an adsorption-desorption
process. Design and
optimization of this storage will be supported by
numerical simulations of
heat and mass transfer with KARDOS. This paper focuses on
the unsteady heat
transfer during the major operating step of energetic
discharge of the
storage, which is characterized by conductive heat
transfer in the fixed bed
and a strong heat source caused by the adsorption
enthalpy. Results are
interpreted concerning the influence of variations in the
parameter set. The
method of implementation of the differential equation will
be shown as well
as the post-processing and gridwriting programs.
