Abstract
Large eddy simulation (LES) and direct numerical simulation (DNS) were carried out for flow and scalar transfer of a round jet. Simulated domain includes transitional and established fields. In LES, Smagorinsky model was used as subgrid scale (SGS) model. Validity of the simulation was examined through comparison between existing experimental literatures and computational results with and without SGS model. Instantaneous structures of vortices and temperature field for Reynolds numbers Re=1200 and 10000 were found to have similarity regardless of Reynolds number.
