ISOTHERMAL DEPOSITION OF DROPLETS AND NANOPARTICLES FROM THE INCIDENT GAS JET ONTO A SUBSTRATE

By computational-hydrodynamics methods the authors have investigated the fi eld of the gas velocity in the fl ow 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 fl ow above the substrate by the action of the external electrostatic fi eld. A study has been made of the infl uence of Brownian diffusion on the nanoparticle deposition from the laminar radial fl ow above the substrate. The authors have introduced similarity numbers for these problems and have determined their infl uence on the effi ciency of deposition.
