Abstract

Abstract

The spatial stability equation of moving jet containing dense suspended solid particles was derived out by means of the continuum phase-coupled model.The stability curves of moving jet for different downstream distances,Reynolds number of flow-field,particle properties and velocities of jetting device are got by the finite difference method based on the asymptotic method and the Eulerian conservative difference scheme.Founded on the analyses of the obtained stability curves it is found that the positive velocity of jetting device widens the unstable frequency range of flow-field but the effect of the negative one is contrary.In addition,particles existing in the flow-field curb the instability of flow-field and the effect enhances with the decrease of Reynolds number of flow-field.These conclusions benefit learning the development of moving two-phase jet.
