  • In this paper,the three-dimensional vortex filament method was used to simulate the evolution of vortex structures in the axisymmetric round jet.The results agree well with the ones given by Chung and Troutt.Then one-coupling model was employed to calculate the particle motion based on the computed flows.The results show that the particle motion is affected by flows obviously at the case of particle number St 1 and negligibly at St 1,particles distribute around the vortex structures uniformly at St~1.When perturbations with wavenumber 5 are introduced to vortex rings, particles disperse wider along radial direction,which conforms to the experimental results.The degree of particle dispersion is in the direct ratio to the amplitude of perturbation.The conclusions given in the paper are useful to the practice usage.
