In order to calculate the pressure pulsations in pipelines in a frequency domain, it is necessary to linearize the velocity-squared nonlinear damping, under the condition that the flow in the pipe is periodic, but not sinusoidal. The authors have proposed a theory for the equivalent linearization in such cases, where two coefficients should be determined : one for the steady-state component of the flow in the pipe and the other for the fluctuating component including all frequency components. To verify the applicability of the theory, the responses of pressure pulsations in a straight pipe were calculated for several known input flows by the transfer matrix method, using three linearization schemes based n this theory. The results were all in good agreement with those calculated by the Runge-Kutta-Gill integration method.
