TL;DR: A critical review of both experimental and computational studies of round turbulent jets is provided, beginning with the work of Tollmien (1926). as discussed by the authors traces the history, major advances, and various stages that the research community went through over the past 85-odd years, from statistical analyses through to the use of conditional sampling, proper orthogonal decomposition and structural eduction methods.

TL;DR: In this article, the effect of the Reynolds number on the near and intermediate-fields region (0,⩽,x/D, ⩽ 25) of a round free jet was investigated.

TL;DR: The flow in the ETA is shown to be highly three-dimensional, having strong secondary flows, and flow features predicted by numerical models are compared to those from experimental flow-visualisation studies.

TL;DR: In this paper, the lattice Boltzmann method (LBM) was used to conduct a direct numerical simulation study of the airflow inside an idealised human upper airway, and the results from both a modest and an extreme resolution (148 million control volumes, 800 Gb data set) LBM simulation were compared to those from experimental results.

TL;DR: In this paper, a comparison of data obtained from the application of these tools reveals many inconsistencies that are explored in this article, while much progress has been made to understand some of the physics of the flow in the human airway, uncover new and significant fluid dynamic behaviour.
