摘要：
Based on the idea that not only the fluid mechanism but also the movement of the particles affects the character of the multiphase now, a new two-way coupling model is developed. Then it is applied to the numerical simulation of the vortex pairing in a mixing layer and it is found that the particles impede the process of vortex pairing and reduce the Reynolds stress; the particle with relative small Stokes number moves with the now and the particle with relative large Stokes number moves towards the edge, but the centrifugal tendency is delayed as compared with the one-way coupling model.
