ANALYSIS OF HEAT-TRANSFER IN A NONISOTHERMAL SOLID-GAS REACTING MEDIUM

This article concerns the thermal phenomena occurring in a reacting solid-gas porous medium. The practical application envisaged is the use of these media in chemical heat pumps (CHPs). The procedure chosen allowed us to almost totally separate the determination of the kinetic characteristics of the medium, presented in the previous article, from the study of the thermal phenomena presented here. The thermal parameters were estimated or identified, depending on their influence, quite satisfactorily. Moreover* we show that it is possible to exploit more limited experimental data, by modifying the procedure, to obtain a sufficiently good understanding of the reacting medium. This technique was applied in the study of the effect of mixing a conducting binder with the medium on its thermal parameters. This model is also used to test configurations having different thicknesses of the reacting bed. © 1991, Taylor & Francis Group, LLC. All rights reserved.
