Abstract
Large Eddy Simulation (LES) of turbulent free round jet submerged in water has been performed at Reynolds number Re = 25 000. LES results are compared against the PIV measurements data for the same flow configuration. The processes of the mixing layer formation in the jet initial region and its evolution downstream have been studied with the analysis of turbulent power spectra. The effect of the subgrid Smagorinsky model coefficient CS on the jet hydrodynamics has been studied.
