Gas-particle motion in 90 and 180-deg bends of circular cross-section is studied using a CFD code. The effect of turbulent dispersion on the particle trajectories is taken into account using a stochastic model. Results indicate that the curvature-induced secondary flow in the gas phase can have a significant effect on the particle motion so that small particles may come out of the bend without depositing. The effect of turbulent dispersion is mainly to increase the likelihood of deposition of small particles.
