| Abstract: | This paper is concerned with the stability of gas-particle two-phase swirling jet. Through theoretical analysis, with an instability model with two controling parameters, the growth rate of disturbances and the related modified Reyleigh criterion of stability are obtained for three different form of noncontinuous distribution of suspended particles. On this basis, the effects of properties of suspended particles and disturbances on the stability of the two-phase swirling jet are analyzed and the curves of flow rate for different cases are presented, which lays the foundation for engineering applications and further investigation of two-phase swirling jet. |
