A method to examine the influences of inlet wetness fraction and inlet angle on the strength performance of the rotating blade considering the effects of wet steam non-equilibrium condensation was proposed. A wildly verified numerical model was employed to simulate the wet steam flow to obtain the pressure distribution on the blade surface. Based on the finite element method, the strength analysis was carried out. Results show that the von-Mises stress of the rotor blade would increase with the inlet wetness fraction and the inlet angle. The sensitive range of studied inlet condition is located at Ain ϵ [0, 15] Win ϵ [0.03, 0.04], in which the increases of the von-Mises stress are over 40%.
