Numerical Simulation of Flow in De-NOx Catalyst Honeycomb with NOx Reduction Reaction

摘要：

The effect of flow behavior in a De-NOx honeycomb with NOx reduction reaction is investigated by direct numerical simulation (DNS).As the inlet flow,fully developed turbulent or laminar flow is given.The results show that the surface reaction is strongly affected by inner flow behavior.The surface reaction rate for the turbulent flow is higher than that for the laminar flow.This is due to the difference of inner flow behavior that the diffusion of NOx in the vicinity of the wall is dominated only by molecular diffusion for the laminar flow,whereas it is enhanced by turbulent motions for the turbulent flow.Moreover,surface reaction is suppresed towards downstream even though inlet flow is turbluent.This is due to the flow transition from turbulent to laminar.
