Abstract

A plane air mixing layer loaded with spherical glass particles is simulated by the three-dimensional vortex method proposed for gas-particle two-phase free turbulent flow by the authors in a prior study. The vortex method computes simultaneously the behavior of vortex element and the particle motion by the Lagrangian approach. It is demonstrated that the simulated particle distribution, mean velocity and fluctuating velocity agree with the measurement and that the vortex method is indeed applicable to the analysis of particle-laden plane mixing layer. The change in the vortical structure due to the loaded particles is also discussed.
