| Abstract: | An elaborate experimental set up is described that was used to measure the thermal expiration curves of heat recuperators, that had been constructed with guard heaters and vacuum insulation to minimize heat losses. A much more general model is used along with a precision numerical analysis technique to show that a film coefficient correlation of the Dittus-Boelter type did an excellent job of representing the results from 162 runs in which three feed gas temperatures, two flow rates, two particle size ranges, one bed diameter and five desciccants were used. For comparison sake the reported film coefficient correlation is finally assembled in a table along with others found in the literature. |
