Abstract

We have performed an experimental study on the influence of the densimetric Froude number on the statistics of the velocity fields of jets issuing from a round, sharp-edged orifice, by means of a novel technique, namely Feature Tracking Velocimetry (FTV). The velocity and turbulent kinetic energy profiles orthogonal to the jet axis, the mean streamwise centreline velocity decay, and the integral turbulent kinetic energy along the jet axis have been measured and analyzed.
