The trajectories of aerosols are computed in a high‐resolution direct numerical simulation of turbulent flow in a vertical channel. The aerosol equation of motion includes only a Stokes drag force and the influence of the aerosols on the gas flow is assumed to be negligible. Since the flow is vertical, aerosols deposit as a consequence of the turbulent fluctuations and their own inertia. Aerosol Deposition from Turbulent Airstreams in Vertical Conduits. Report BNWL, Battelle Memorial Institute, Richland, Washington, USA. CrossRef Google Scholar. Progress to the correlation of particle deposition velocity in turbulent pipe flow is presented. The developed model accounts for the Brownian diffusivity and inertia effects and is extended to cover the influence of the flow velocity by including Reynolds number in the correlation. The experimental data and previous proposed models are used in comparison of predicting particle deposition rate.   Experimental Observation of Aerosol Deposition in Turbulent Flow,” Google Scholar.

In this work, aerosol deposition from turbulent air streams in vertical and hori-zontal ducts is studied. The turbulent flow eld is generated by the direct numerical simulation of the Navier{Stokes equation.
