Study on Characteristics of Gas Flow Velocity in Catalytic Converter with Porous
This paper studies the different porosity of porous medium how to affect the flow velocity field under the conditions of same inlet velocity and fiber diameter by CFD method. Geometric model of the catalytic converter has been established and meshed by the pre-processing tool FLUENT. The flow speed simulation filled contours and velocity distribution curve of the fiber porous material show that reducing properly the porosity may improve the uniformity of the velocity in Y and Z direction of the porous material. The less porosity is beneficial to exhaust catalytic reaction.
