Description
Summary:AbstractComprehensive laboratory experiments on multiport diffusers for dense effluents such as brine into stationary receiving waters are reported. Tracer concentration fields were mapped in three dimensions by laser-induced fluorescence (3DLIF). The effect of port spacing is described by s/dF where s is the port spacing, d the nozzle diameter, and F the jet densimetric Froude number. For s/dF>∼2, the jets did not merge, and the results followed expected asymptotic solutions for single jets. For s/dF∼2.
