| Abstract: | The primary goal of this paper is to discuss the engineering application of the bowed and twisted blade on sub-last and last stages of steam turbines. The S2 stream surface direct problem calculation based on the solution of Euler equations is used for the through flow design with the bowed and twisted blade.The stationary cascade experiments are conducted on the annular cascade wind.According to the analyses of both predicted and tested results,the paper discusses the effect of the bowed and twisted blade on the improvement of the flow field in sub-last and last stages of steam turbines. |
