Twodimensional mathematical model of a nonbuoyant jet in a crossflow
Abstract
The mean velocity distribution for the mixing of a turbulent, nonbuoyant, round jet in a cross wind is calculated using a twodimensional mathematical model (on the plane of symmetry) based on a linear superposition of the developments of the jet, the two bound vortices formed from the rolling up of the vorticity in the initial stage of the jet, the wake behind the bent jet, and the freestream. The results of the mathematical model are compared with measurements of the mean velocity on the same plane of symmetry. These comparisons, which are performed for a jet to freestream velocity ratio of 3.87 and a jet Reynolds number 47,400, show a relatively good firstorder agreement between the model and the experimental results. The analysis includes prior models of centerline geometry and mean speeds, and extends the predictions of mean speeds to the entire plane of symmetry where the jet centerline is located.
