摘要

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. The coherent structures within the turbulence were identified with plots of the discriminant. Two or four tabs compressed the flow regions containing structures, increasing the strength of the vorticity. These results demonstrate the potential for using large eddy simulation to aid in the design of efficient jet nozzles.
