Brownian motion and the drift of charged nanoparticles in laminar gas flow in a plane channel

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Using two limiting cases (of adsorbing and reflecting channel walls), the influence of Brownian motion on the motion of nanoparticles in laminar gas flow under the action of an external electric field has been considered. Similarity criteria making it possible to classify experimental situations have been found. Numerical modeling of deposition from the flow has been carried out with the example of the motion of a monodisperse ensemble of spherical nanoparticles with a radius of 3 nm.
