Abstract
Abstract Non-spherical particle deposition in a vertical turbulent channel flow is studied using large eddy simulation and a stochastic Markov model that represent the effect of unresolved sub-grid scale fluctuations on particle dispersion. A Lagrangian particle tracking algorithm, accounting for drag, lift, gravity and Brownian forces, as well as particle shape, orientation and rotation, is developed and used to predict particle deposition. Results show good agreement with measurements, demonstrating that the characteristics of the flow and particle force balance are well captured, and the effects of particle shape and orientation are demonstrated.
