中文摘要	Turbulent round jet flows were analyzed with and without inlet perturbations using large eddy simulations (LES). The evolution of the large vortex structures and the statistical properties including the streamwise velocity and the turbulence intensity from the simulation were compared with and without inlet perturbations and then with experimental data. The results show that the simulation with the inlet perturbations is superior to that without inlet perturbations in terms of physical reality and accuracy. The results show that the actual turbulent round jet flow must be simulated by a three-dimensional analysis with inlet perturbations.
