摘    要:采用考虑悬浮固粒与气流相互作用的Marble压力耦合模型和涉及悬浮固粒容积系数与平均固粒雷诺数的修正斯托克斯阻力公式,得到了含悬浮固粒的旋转射流稳定性控制方程及相应的修正瑞利稳定性准则.通过计算,给出了不同团粒属性及气相跳跃速度下旋转射流的增长率和发展系数曲线,根据所得稳定性准则,得到了固粒属性对旋转射流稳定性影响的重要结论,文中结论为工程控制旋转射流场及后续发展提供了理论依据.

关 键 词:稳定性  旋转射流剪切层  悬浮固粒  压力耦合  数值计算

Abstract:In this paper, the control eqution of stability of - gas jet contahang suspended solidparticles and the cormsponding medified Raytigh stability criterion are ohtalned on the basis of the applicahonof Marble pressare coupling medel and whilied Stokes for law induced by the large particle voume hachonand mean Particle Renolds ntunber. The ed rate curves and development coefficient curves of gas-particleswirling jet for different PaIticle proPerties and gas jump velocihes are got by means of ntimerical comPutahonand then several Anportant conclusions on effect of particles on stability of swirling gas jet, which provide use-ful theorehc evidences to contIDs over swirling gas jet and its subsequent develoPment in eopneering prsctice,are achieved based on the analyses of the varied curves according to the obtained stability criterion.
Keywords:stability swirling jet shear layer suspended solid particle numerical computation
