A model for particles deposition in turbulent inclined channels

摘要: Abstract A computational model for studying the deposition of particles in duct flows presence thermal force under turbulent flow condition was developed. The V2F turbulence used to evaluate mean and temperature fields, as well root mean-square fluctuation velocities. selected due its potential accurate evaluation intensity velocity fluctuations normal wall. instantaneous field simulated with use Kraichnan continuous Gaussian random anisotropic intensities generated by model. Lagrangian particle trajectory evaluating transport particles. Stokes drag, lift, Brownian, gravity thermophoretic forces were included equation motion. predicted velocities vertical horizontal ducts absence thermophoresis effects compared available experimental data earlier empirical models, good agreements found. series simulations on lower surface an inclined different imposed gradient fields performed. developed models extended thermophoresis. simulation results shown be agreement predictions.
