摘要

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,进而得到了关于固粒对流场中扰动增长和传播的影响及失稳过程中固粒扰动特性的结论。这些结论对于两相射流发展的认识和工程实际中实施对两相射流场的人工控制有重要意义。

Abstract: 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.
