Abstract

In this project the object is to apply the principles of Residence Time Distribution (RTD) analysis to the study of free convection in porous media. The advantages of this technique are that it is non-intrusive, the data are quickly generated, and a large amount of information, distributed in the time domain, is obtained. The disadvantage is that a model must be used to infer the flow pattern from the RTD. It is proposed to apply the same modeling approaches that have been used successfully in mixing tank studies and to interpret the flow patterns in terms of similar mixing tank model parameters. Correlations would then be sought with global parameters of the porous medium like Rayleigh, Peclet and Nusselt numbers. 2 refs., 3 figs.
