Heat and Mass Transfer Analysis within a Disc-Shaped Fluidized Sorption Reaktor

Popis výsledku v původním jazyce

The depletion of fossil fuels and increased greenhouse gas emissions are crucial factors forcing innovation in various branches of industry and life. In the 21st-century air conditioning is becoming a necessity in terms of well-being and health. Therefore, adsorption cooling technology constitutes a very promising alternative to energy-consuming and environmentally hazardous vapour compression chillers. The main challenge in the wider popularization of adsorption technology is the intensification of heat and mass transfer within the adsorption bed. Therefore, the paper presents different sorption reactor concepts aimed at solving the aforementioned issue. The main parameters influencing heat and mass transfer for each of the analyzed cases are calculated using the computational fluid dynamics code adapted to capture the specific phenomenon occurring in the adsorption bed. The developed numerical model is validated against the experimental data collected on the test stand dedicated to experimental research of innovative adsorption beds operating in various conditions. The results of numerical modelling with the use of the developed coupled CFD &amp; DEM model concerning the adsorbent particles movement and variation in relative temperature of the adsorbent within the fluidization process are presented in the paper. The research allowed to define the design parameters of the adsorption bed that allow intensifying the heat and mass transfer in the adsorption reactor and, in consequence, significantly contribute to the development and popularization of the adsorption cooling technology.
