| Abstract: | The impacts of structural changes of small diameter tube under multi-step bending on gas flow characterisitcs were studied by multi-step bending experiments and CFD numerical simulation, and the structural changes of small diameter tube were analyzed. The three dimensional models which could simulate experimental state were established, and the impacts of structural changes on gas flow characterisitcs were obtained. |
