THC-Processes

Abstract

The operation of thermochemical heat storage devices in open mode by permeating a reactive porous body or particle bed by a compressible heat-transfer fluid which in turn transports a reactive fluid component constitutes a strongly coupled problem of multiple physical processes. High reaction rates associated with a rapid release of significant amounts of heat and a complicated dependence of processes and material properties on the physical and chemical state of the system add to the level of complexity. It is the purpose of this chapter to (i) define a suitable benchmark for a suitable process model and (ii) perform such a comparison by using the simulation platforms OpenGeoSys, DuMux and ANSYS Fluent.
