This proposal is concerned with unsteady fluid flow in pipeline systems         in which the wave propagation velocity is frequency dependent, rather           than constant.  The proposed solution procedure operates in the                 frequency domain where well established frequency response and free             vibration analyses will be modified to analyze periodic motions                 incorporating the frequency-dependent wavespeed.  Additionally, the             impulse response method, incorporating the Fast Fourier Transform, will         be used in the solution of nonperiodic transient cases.  Both linear and        nonlinear transfer function techniques will be utilized.                        The linear and nonlinear impulse response method provides an attractive         alternative for hoses, tubes and pipelines that display a                       frequency-dependent behavior. Applications are numerous in many                 industries that rely on hydraulic control lines to provide energy               transmission to actuators on machine tools, robots, heavy equipment,            transportation vehicles, etc.  Long oil, gas, and water transmission            pipelines, and tunnels in hydropower schemes often display a                    frequency-dependent behavior.  The methods in this proposal are                 taylored to address these topics for these industries.
