SINOPSIS
Large eddy simulation was used to calculate the effects of vortex-generating tabs on the turbulence structures in the near field of a round jet. Alterations in the shape of the ring-shaped structures were observed. Changes in the rate of flow entrainment were related to the presence of large-scale braid-shaped structures formed as a result of the tabs. These preliminary results demonstrate the potential for using large eddy simulation to aid in design of efficient jet nozzles.
