Abstract
Most integral models that have been developed to compute buoyant jet mixing in flowing receiving fluids ignore any contribution of ambient turbulence to the jet mixing process. Any justification for this approach is based on a very limited data set. This study considers the effect of ambient turbulence on the mixing of a nonbuoyant co-flowing jet. Existing models are reviewed to determine which one best reproduces observations in ambient fluids with low turbulence levels. This model is then combined with a hypothesized mixing relation that accounts for the ambient turbulence and the resulting model is shown to reproduce the mixing observed in various experimental data. The results of this study imply that ambient turbulence will have a relatively significant influence on jet mixing for applications in which the primary jet motion is in the direction of the ambient current.
