摘　　要：用连续介质耦合模型推导出含高浓度悬浮固粒运动射流的空间稳定性方程，然后用渐进分析法和有限差分得到不同流向位置、喷射装置运动速度和固粒属性时流场的稳定性特征曲线。说明流向位置、喷射装置运动速度和固粒属性对流场稳定性的影响。本文结论对于工程应用有指导意义。The spatial stability equation of moving jet containing dense suspended particles is derived out by means of the continuum phase-coupled model. The asymptotic and finite difference method are used to obtain stability curves for different downstream locations, velocities of jetting device and particle properties. The effects of downstream locations, velocities of jetting device and particle properties on the stability of flows are illustrated. These conclusions are benefit for the practice usage.
