| Abstract: | Using the dimensional and similarity analysis in a combination with the method of matched asymptotic expansions, the problem
of particle deposition on boundaries in high-Reynolds number turbulent channel flows is studied. Based on the conventional
two-layer scheme of a turbulent near-wall flow, the relations for the distributions of the particle concentration and the
velocity fluctuation moments in the wall region are obtained. Asymptotic laws are derived for the particle deposition rate
for diffusion-impact and inertial deposition regimes. |
