Notizen:
The response of a packed bed to a sine wave of temperature in a stream of fluid through it will depend upon the amount of dispersion in the resistance to transfer between fluid and solid, and the thermal properties of the soild. A method is presented that allows the effects of these three phenomena on the amplitude and phase angle to be unravelled and hence all their magnitudes to be computed simultaneously. It thus presents a way of determining these three quantities in situations where they were previously obtainable either with great uncertainty or not at all. The method requires measurements of the relative amplitudes and phase angles at three frequencies, and (preferably) at ω → 0 as well, all to be carried out with high accuracy.
