Predictions for particle deposition from LES of ribbed channel flow

Predictions for the deposition of spherical and cylindrical particles from a ribbed channel flow onto adjacent flow boundaries are obtained using large eddy simulation (LES) under the assumption of one-way coupling. Results indicate that spherical particles tend to accumulate on the vertical rib wall facing the mean-flow direction with little particle deposition onto surfaces immediately downstream of the rib. This preferential deposition is not predicted for cylindrical particles.
