... excitation of two-phase flow. In the analysis of turbulence excitation, it is necessary to determine the random turbulence excitation based on the dimensionless reference equivalent power spectral density (EPSD), the flow parameters of the secondary side and the correlation length. In single-phase flow...

... summation rule. In design process, the fluctuation of load is usually characterized through power spectral density (PSD). Therefore, the design process is expected to be generalized if the fatigue damage is directly evaluated from the PSD together with S-N diagram of the material. In fact many properties...
