Characterization of Particulate Matter and the Capture Efficiency
Journal article, 2016

The capture efficiency (CE) of particulate matter in a novel metal substrate was evaluated using an exhaust gas after treatment system rig. The CE was measured for different temperatures, flows and channel lengths. The trends of CE showed the expected behavior as the CE increased for higher temperatures, lower velocities or longer channel lengths. The experimental results were compared against theoretical calculations of different types in order to visualize and interpret the observed CE in the novel metal substrate. Computational fluid dynamics simulations investigations indicated that inertial mechanisms on particle deposition were active in the metal substrate. It was also demonstrated that the channel length was the most significant factor for increased CE.
