Type of article: Article

Summary

THE APPROXIMATION USED RELIES ON THE FACT THAT THE DIMENSIONLE SS PARAMETERS, KNOWN AS THE REDUCED PERIODS, ARE NOT TOO LARGE, A CONDITION WHICH IS MADE MORE PRECISE IN THE PAPER, AND WHICH IS TRUE FOR ALL POWER STATION AIR HEATERS. THE METHOD PREDICTS THE VARIATION OF FLUID AND HEAT EXCHANGE ELEMENT TEMPERATURES WITH POSITION AND TIME. IT IS GENERALIZED TO COVER THE CASE OF A REGENERATOR. THE RESULTS ARE COMPARED WITH A FINITE DIFFERENCE SOLUTION. THE ABILITY OF THE METHOD TO COPE WITH LONG REGENERATORS IS ALSO DEMONSTRATED.
