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.

Velocity measurements were made in two jet flows, the first exiting from a smooth contraction nozzle and the second from a long pipe with a fully developed pipe flow profile. The reynolds number, based on nozzle diameter and exit bulk velocity, was the same (≃86,000) in each flow. The smooth contraction jet flow developed much more rapidly and approached self-preservation more rapidly than.
Jun 14, 2018 the exhibition methodology was based on the underlying nature of experimentation shared by both scientists and artists.
An approach to measure and model turbulent flows in complex configurations is presented. It is based on the synergistic use of two novel techniques: the experiments are based on magnetic resonance velocimetry, which allows the collection of a large three-dimensional volume of three-component velocity measurements in a short period of time.
Measurements of the velocity and turbulence characteristics of a round turbulent jet in crossflow are reported.
