Abstract:

The performance of a deep and stratified mixing channel is assessed theoretically and experimentally. The channel has a rectangular cross-section, a negligible longitudinal slope and is directly connected to a large body of ambient fluid. The flow consists of a mixing region and a gradually varied region. A possible three-dimensionality of the mixing region is considered. The main objective of the study is to provide a method to predict the dilution of a discharge in a mixing channel of specified length, width and roughness. In a shallow mixing channel the vertical confinement effect on the mixing behavior can be significant and would have to be taken into account as explained in Baddour (1987a).
