The Mechanism of Heat Transfer within Soldered Packed-bed in a Flow System

Heat transfer within soldered packed-bed in a flow system was assumed to have two processes, namely: (1) heat transfer like a fin, and (2) heat transfer like an ordinary packed-bed. Next, the differential equations about this cylindrical type of the bed were obtained as follows: (1)(2) Temperature d...

Summary:Heat transfer within soldered packed-bed in a flow system was assumed to have two processes, namely: (1) heat transfer like a fin, and (2) heat transfer like an ordinary packed-bed. Next, the differential equations about this cylindrical type of the bed were obtained as follows: (1)(2) Temperature distributions were measured in detail with 5 samples of heat transfer units having 11mm. dia. steel balls soldered at different heights within 5″ dia. brass tubes and Eqs.(1) and (2) were checked by graphical differentiation of these temperature distributions, and the values of hpat were obtained. They gave almost the same values. Therefore, the assumption mentioned above on the mechanism of heat transfer in soldered packed-bed could probably be maintained. The hp values obtained had good agreement with those in literature.
