The inner flow field of TWC with different structural parameters is introduced and the mathematical model of the inner flow field of TWC and carried on the simulation of inner flow field of TWC through using the CFD software-FLUENT is built. The regulations about velocity and press distribution on head face of carrier is obtained . The solution that the long-short model is an ideal improvement scheme is worked out by comparison.
