Vortex methods have been thus far applied to simulate gas-particle free turbulent flows, such as mixing layer, wake and jet, to investigate the particle diffusion due to the vortex structure of the gas-phase. The simulations are performed only under low mass loading ratio, because the vortex methods are based on a one-way coupling between the two phases. This article describes a two-way vortex method proposed by the author. The gas flow and the particle motion are simultaneously calculated by the Lagrangian method. The applicability of the method is also demonstrated by presenting the numerical simulations of a particle-laden mixing layer and a slit nozzle gas-particle two-phase jet.
