NON-DARCIAN NONISOTHERMAL COMPRESSIBLE FLOW AND HEAT-TRANSFER IN CYLINDRICAL PACKED-BEDS

Knowledge of transport processes is of considerable practical importan ce in the design and performance evaluation of packed bed reactor syst ems. Acquisition of the required information necessitates a realistic mathematical description of the system. In this study, numerical analy sis is performed for forced convective non-Darcian, non-isothermal com pressible flow and heat transfer in cylindrical packed beds. Local str uctural and transport properties are considered. The influence of comp ressional work as well as viscous dissipation on the thermal field is evaluated and a general criterion provided for assessing the effect of expansion.
