摘要: Dispersion and deposition of particles in a turbulent channel flow with rough walls are studied. A procedure for simulating the aerosol on surface is developed. The instantaneous field generated as sum mean randomly fluctuating Gaussian field. Particle equation motion including effects Brownian diffusion, Saffman lift force, gravity solved numerically. Starting an initially uniform concentration near wall, ensembles particle trajectories statistically analyzed. Several simulations various sizes performed corresponding velocities evaluated. results compared those obtained by empirical equations experimental data
