Abstract: | This article reviews measurements for the canonical flow: incompressible turbulent round jets issuing into a large, ideally
infinite, quiescent domain. The available far-field data on mean velocity, momentum-flux conservation, Reynolds stresses and
triple fluctuation correlations are presented. The budget equations for turbulent kinetic energy and for the individual Reynolds
stresses are shown, including different formulations for dissipation and pressure-velocity correlations. Evidence of the persistence
of source conditions in the self-preserving far field is observed in several cases. This article analyses and compares several
data sets, obtained at different levels of detail, against analytical constraints, discusses limitations and provides insights
aided by reference to recent numerical work. It is hoped that this will prove useful in guiding future experiments and numerical
test cases, where complete details of the jet configuration are required for validation and comparison. |
