| Abstract: | In this article a catalytic converter interior flowing model for the globose end surface carrier was established,which can carry on the three-dimensional numerical simulant computation to its internal flowing field,analysis the velocity distribution and the pressure losing situation.Then a conclusion can be obtained that the flowing quality of the globose end surface carrier is better than the vertical end surface carrier,which provides an important information for how to further improve and optimize the carrier structure. |
