| Abstract: | The geometrical modeling and numerical simulation were made for the LP exhaust hood of steam turbine,so that the inner 3D viscous flow has been numerically calculated by CFD software and the loss distribution of the exhaust hood has been analyzed.By analyzing the flow-field of the exhaust hood carefully,the reason of flow losses was reviewed to provide the reference for the design of the other steam turbine exhaust hoods. |
