Abstract

Exact results are derived for the centroid and longitudinal variance of a passive contaminant distribution at large times after an instantaneous discharge in an oscillatory flow in a straight channel of constant cross-section. It is shown that the precise timing and cross-stream position of the discharge can have a substantial and persistent influence.
