چکیده انگلیسی
The effects on particle dispersion by turbulence transition in a three-dimensional plane jet are investigated by means of direct numerical simulation. The governing equations of fluid motion are solved by a finite volume method and a fractional-step projection scheme. The particles are traced in the Lagrangian framework. It is found that the transition phenomenon of particle dispersion occurs during turbulence transition for particles at certain Stokes numbers. For particles at the intermediate Stokes numbers of 1 and 10, the dispersion changes from non-uniform to uniform patterns. These transition behaviors of particle dispersion reflect the self-selective mechanism between multi-scale structures in turbulent flows.
