Abstract

The process of turbulent migration of liquid aerosol particles in a chaotic packed bed of a gas separator is considered. Differential equations for the mass transfer of particles in plane-parallel and cylindrical channels, as well as in an apparatus with a chaotic packed bed, are written. The nonuniformity of the gas velocity profile at the inlet to the bed and further in the packed bed is taken into account by the local volumetric source of the mass of deposited particles on the surface due to the turbulent-inertial mechanism, as well as by the coefficient of turbulent diffusion of particles. Expressions are given for calculating the parameters of the mass source associated with the dynamic velocity on the surface of the packed bodies. The results of the numerical solution of the equation of mass transfer of particles with a uniform and nonuniform profile of the gas velocity at the inlet are presented. It is found that unevenness reduces the efficiency of particle separation, which must be taken into account in calculations when designing apparatuses. Conclusions are drawn about the most effective packing designs.

考虑到气体流速分布的不均匀性，确定液滴的填充气体分离器的效率

摘要

考虑了液体气溶胶颗粒在气体分离器的混沌填充床上的湍流迁移过程。编写了在平面平行和圆柱状通道中以及在带有混乱堆积床的设备中用于粒子传质的微分方程。由于湍流-惯性机制，由于表面上沉积颗粒的质量的局部体积来源，考虑了在床入口处以及进一步在填充床中的气体速度分布的不均匀性。颗粒的湍流扩散系数。给出了用于计算与填充体表面上的动态速度相关的质量源参数的表达式。给出了在入口处具有均匀和不均匀的气体速度分布的颗粒的质量传递方程的数值解的结果。发现不均匀性降低了颗粒分离的效率，在设计设备时必须将其考虑在内。得出有关最有效包装设计的结论。
