Mixing, intermittency and large eddy simulation of a turbulent round jet
Mixing, intermittency and large eddy simulation of a turbulent round jet
Large Eddy Simulation (LES) is a promising technique for accurate prediction of turbulent free shear flows in a wide range of applications. Here the LES technique has been applied to study the intermittency in a high Reynolds number turbulent round jet in a co-flow environment. The objective of this work is to study the external intermittency of velocity and scalar fields. LES based time averaged statistics show good agreement with the experimental measurements. The calculated probability density distributions show a Gaussian shape near the centreline region and a delta function at the furthest radial locations. The agreement between LES results and experimental data are good for the external intermittency indicating that the dynamic LES subgrid model accurately predicts the external intermittency.

Abstract
Large Eddy Simulation (LES) is a promising technique for accurate prediction of turbulent free shear flows in a wide range of applications. Here the LES technique has been applied to study the intermittency in a high Reynolds number turbulent round jet in a co-flow environment. The objective of this work is to study the external intermittency of velocity and scalar fields. LES based time averaged statistics show good agreement with the experimental measurements. The calculated probability density distributions show a Gaussian shape near the centreline region and a delta function at the furthest radial locations. The agreement between LES results and experimental data are good for the external intermittency indicating that the dynamic LES subgrid model accurately predicts the external intermittency.
