A mathematical model for heat transfer in a packed bed and a simplified solution thereof

Abstract

first necessary to investigate the heat transfer characteristics of the packed bed system and to consider all the effective modes of transfer of heat that are known or suspected to occur. It is well known that the heat transfer coefficient from the particle to the gas phase cannot be established without assuming some mathematical model for the process. The coefficient depends upon the model assumed. In any adequate model there will usually be several adjustable parameters that describe the pysical attributes of the system. Unfortunately, models that are
