| Abstract: | in this paper, based on a single stage axial now fan cooling the 300 MW turbine-generator, a theoretical study and experimental analysis are made of the add-straightener and the non-guider respectively. the twisted destribution of the fan blades is obtained by the optimum method. In addition, the selection of the Dt, Dh/Dt is also investigated. |
