Simulations of Trapping of Diesel and Gasoline Particulate Matter in Flow-through Devices
Artikel i vetenskaplig tidskrift, 2009

Eulerian–Lagrangian CFD modeling has been used to track eight types of typical diesel and gasoline soot particles through a flow-through substrate with protrusions. It is shown that there exists a minimum trapping efficiency for medium-sized soot particles (dp ≈ 150 nm). Small and large particles are trapped by different mechanisms, and thus appear in different patterns on the substrate walls.
