Combining transient blade row (TBR) method with stationary inverse Fourier transformation (IFT), an effective method for numerical simulation of flow-induced force on the blade at the last stage of steam turbine is proposed in this study. Using this method, only a single flow channel needs simulating transiently to obtain the force on blade. Then, the numerical simulation of flow-induced force using this method is carried out on the last stage of a real steam turbine, and the feasibility of this method is also verified via this example. Comparing with traditional transient computation, a remarkable amount of computing time and resources can be saved by this method.
