Abstract
The process of soot trapping in a hexagonal cell geometry diesel particulate filters (HEX DPF) in surface pores filtration made of aluminum titanium oxide were investigated through a simple analysis based on Darcy’s law through the wall and deposited soot layer. In this study, we focused on the trapping process of the HEX DPF cell in surface pores filtration by Numerical Simulation. The HEX DPF had two types of flow: one was a flow through a wall between inlet and outlet channels (inlet/outlet wall flow), and the other was a flow which was introduced into a wall between inlet and inlet channels, and was turned toward the direction parallel to the wall, and finally exited into the outlet channel (bypass flow). As a result, the process of soot trapping in surface pores filtration was shown by numerical simulation. It was possible to express the transition process from surface pores filtration to cake filtration.
