Models of Thermochemical Heat Storage [Paperback]

Thermochemical gas-solid reactions, as well as adsorption processes, are currently of significant interest for the?design of heat storage systems. This book provides detailed models of these reactions and processes that account for heat and mass transport, chemical?and physical reactions, and possible local thermal non-equilibrium.?The underlying scientific theory behind the models is explained, laboratory tests are simulated, and methods for high-performance computing are discussed.?Applications ranging from seasonal domestic heat storage to diurnally operating?systems in concentrating solar power facilities are considered in these models, which are not available through any other sources.?Finally, an?outlook on future developments highlights emerging technologies.Introduction.- THC Processes in a Packed Adsorbent Bed.- The FEM Simulation Software OpenGeoSys 6.- Laboratory-Scale Adsorption Chamber Simulation.- Extensions.- Closing Remarks.

Christoph Lehmann obtained his Bachelors degree in Physics from the Martin Luther University Halle-Wittenberg in 2011 and his Masters in Physics from the University of Leipzig in 2013. Hes been working as a software developer at pwp-systems developing tools for traffic data analysis from 2011-2015. After working on scientific visualisation at the Institute of Computer Science at Leipzig University, he joined the UFZ in 2015 to work on the numerical simulation of thermochemical energy storage (TCES), especially systems based on water adsorption to zeolite. His research interests are the numerical assessment of the energy efficiency of those storage systems and the examination of the sortion kinetics of novel composite adsorbents, in particular zeolite granules impregnated with hygroscopic salts for the enhancement of the heat storage density.
