Résumé

Heat conduction through evacuated packed beds of uniform-diameter spheres between two infinite parallel plates is considered. The structure of the packing is modeled by numerical simulation of individual rigid spheres slowly settling into a randomly packed bed. A Monte Carlo technique is used for the simulation of the conduction process and the treatment of data uncertainty. Heat conduction through the central and wall regions are considered independently due to the packing structure difference. Numerical results from this study are compared with results from other approaches. These results, which can only be compared in the randomly packed section, agreed quite well. The most significant advantage of the present approach lies in its ability to predict the effective thermal conductivity of packed beds for different geometries and particle sizes. This method also gives physical insight into the behavior of the system.
