摘要： Interaction between two different species of particles in a fluid stream is promoted by generating turbulent eddies in the fluid stream. The turbulent eddies are designed to be of such size and/or intensity that the two species of particles are entrained into the eddies to significantly different extents. Consequently, the different species of particles follow different trajectories, and the likelihood of collisions or interactions between the particles is increased. Optimum collision rates will occur for a system which maintains a Stokes Number (St) much less than 1 for one species, and or order 1 or greater for the other species. The invention has particular application in air pollution control, by promoting agglomeration of fine pollutant particles in air streams into larger particles to thereby facilitate their subsequent removal from the air streams.

摘要： Interaction between two different species of particle(s) in a fluid stream is promoted by generating turbulent eddies in a fluid stream. The turbulent eddies are designed to be of such size and/or intensity that the different sized particle(s) are entrained into the eddies to significantly different extents and forced to follow different trajectories, increasing the likelihood of collisions and interactions. Optimum collision rates will occur for a system which maintains a Stokes Number much less than 1 for one sized particle, and or order 1 or greater for the other sized particle. The invention has particular application in air pollution control, whereby agglomeration of fine particles into larger particles is promoted, subsequent to their removal.
