Particle deposition in turbulent duct flows

▸ Particle deposition in fully developed turbulent square duct flows is simulated. ▸ The secondary flow plays an important role in the particle deposition process. ▸ High-inertia particles tend to deposit close to the corners of the duct floor. ▸ Low-inertia particles deposit near the floor centre. ▸ The particle deposition process can be described by the free-flight model.
