Determining the Efficiency of Packed Gas Separators of Droplets Taking into Account the Nonuniformity of the Gas Velocity Profile

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.
