Краткое описание
Budgets of the time-averaged stream-wise vorticity equation are examined in high Reynolds number 3D jets with complex cross-sections. Detailed results are presented from LES data of a rectangular jet. Experimental data are presented for elliptic and triangular jets, which issued from sharp orifices. The results show that the anisotropy of the turbulent stresses play significant roles in the evolution of the jets, in particular, in the axis-switching phenomena.
