Isothermal Deposition of Droplets and Nanoparticles from the Incident Gas Jet onto a Substrate
By computational-hydrodynamics methods the authors have investigated the field of the gas velocity in the flow developed after the turn of the gas jet near the substrate. Consideration has been given to the problem on deposition of charged micron-size droplets from radial flow above the substrate by the action of the external electrostatic field. A study has been made of the influence of Brownian diffusion on the nanoparticle deposition from the laminar radial flow above the substrate. The authors have introduced similarity numbers for these problems and have determined their influence on the efficiency of deposition.
