A plane air mixing layer loaded with spherical glass particles is simulated by the three-dimensional vortex method to investigate the effect of particle on the air vortical structure. The method, proposed for gas-particle two-phase free turbulent flows by the authors in a prior study, simultaneously computes the behavior of the vortex elements, discretizing the air vorticity field, and the particle motion by the Lagrangian approach. The simulation highlights that the loaded particles impose disturbances on the air flow, promoting the transition from the two-dimensional structure to the three-dimensional one. The changes in the air turbulent features due to the particles are also investigated.
