含尘气流中尘粒运动的研究

Study on Motion of the Dust Particles in Two-phase Flow

针对静电除尘器中的含尘气体,分析了二相流中粒子相的扩散运动,并提出了简化物理模型,导出了二相流中粒子相在三类近似条件下的简化运动方程,使定量分析二相流中粒子相的运动成为可能.这种简单实用的方程在除尘器和测尘仪设计中已得到应用.

For the airflow with dust particles in static electricity dust catcher, the diffusion of particles in two-phase flow is analyzed in this paper. The simplified model of two-phase flow is proposed. Three kinds of equations of a particle motion is derived. So it is possible that motion of the particles in two- phase flow can be analyzed quantificationally.
