The investigation of the dynamic behaviour of coupled reaction beds of
thermally driven dry sorption machines with metal hydrides as working
materials is of particular interest due to their cyclic working condi
tions. Development and optimization of such devices require highly sop
histicated computational design methods. The developed mathematical mo
del and numerical discretization method are described. Detailed comput
er simulations of the heat and mass transfer in and between coupled re
action beds show good agreement with experimental results.
