Description

This paper proposes a two-dimensional numerical method for gas-solid two-phase free turbulent flow, which can take account of the interaction between the particle and the gas-phase. The computation of the gas flow by a vortex method and the Lagrangian calculation of the particle motion are simultaneously performed. The change in the vorticity of the vortex element by the viscous effect is simulated through a core spreading method. The change due to the particle is evaluated from the force exerted by the particle acting on the gas-phase using an area weighting method. The present method is also applied to the analysis of a gas-solid two-phase mixing layer. The numerical results, such as the number density, velocity and turbulent intensity of the particle, are favorably compared with the experimental date, demonstrating the applicability of the method.
