摘　　要：利用气固两相耦合模型 ,理论推导出含悬浮固粒射流的稳定性方程 ,通过数值计算得到了两相射流稳定性特征曲线、固气扰动速度比值幅值曲线及固气相位差曲线 。The stability equation of interface of two_phase jet and the corresponding particle_gas disturbance velocity ratio equation are derived by means of the phase_coupled model. The stability curves of interface of two_phase jet for different particle properties and the corresponding particle_gas disturbance velocity ratio curves are given out through numerical computation. Further, several important conclusions in effect of particle property on growth and propagation of disturbance of interface of two_phase jet and particle disturbance property are presented on the basis of analyses of the obtained stability curves and particle_gas disturbance velocity ratio curves. These important conclusions can play a guiding role in studying development of two_phase jet and executing artificial controls over it in project practice.
