Transport processes in narrow channels with application to rotary exchangers

Rotary solid storage elements, combining heat and mass transfer, are used f or dehumidizing air, solvents recovery or separation. The performance of th e rotor mainly depends on its single channels parameters and the type of fl ow material combinations employed as sorbents and carrying structures. The local heat transfer along the ducts was investigated by holographic interfe rometry. Fundamental tests were conducted to determine the loading behaviou r of different rotary heat and mass exchanger samples. In further experimen ts the loading progression of different samples after an increase of humidi ty were determined. Finally a method of the numerical simulation of the com bined heat and mass transfer in rotary exchangers is described briefly.
