A survey of selected literature on important flow properties and computational fluid dynamics treatments of incompressible turbulent plane and round jets in quiescent ambient

Abstract

Turbulent jets are encountered in several practical applications in a large number of fields of engineering. Selected literature on incompressible turbulent plane and round jets in quiescent ambient has been reported in the present paper. These are classified as experimental and numerical works. One objective of the present survey is to report important flow features of incompressible turbulent jets observed by several researchers over a period of four decades. Experimental investigations of important flow properties of both types of jets, such as time-averaged velocity profiles, turbulent stresses, intermittency, growth rates, entrainment and role of coherent structures, transport of heat and passive scalar, higher order moments under a wide range of flow conditions have been reported. Performance and other issues of different turbulence models (both standard versions and modified versions to account for different effects) have also been discussed. Some important literature on large eddy simulations and direct numerical simulations of these flows has also been reported. Important observations from the literature survey have been summarized.
