Dispersion and uptake in a coiled tube.
We have investigated the dispersion characteristics of a highly soluble tracer gas in a coiled tube lined with wet gelatine. Our experiments indicate that absorption and desorption of the gas at the wall dominates tracer dispersion along the tube. The results confirm previous experiments in a branching geometry indicating that the influence of secondary flows on dispersion is reduced if the tracer is very soluble in the wall.
