Durability of Three-Way-Catalyst-Particles Membrane Filter for Fluid-Dynamic Shear Stress

Abstract

Durability of a three-way-catalyst particles membrane filter was investigated experimentally. After manufacturing of the membrane filter similar to trapping of soot, a working-gas flow was changed from a wall flow type to a straight flow type to make a constant shear stress on the surface of the membrane. Then, by integrating the fitting curve of peeling rate obtained from the experimental points from zero to infinite time, the total peeling percentage was calculated.
