Wave propagation in flexible tubes
… of waves is described as attenuation of pressure pulse decay with respect to the frequency or harmonics. In this thesis, wave dissipation, including decay of pressure pulse, peak of wave intensity and wave energy, is investigated in the time domain using wave intensity analysis (WIA). …

LABORATORY-SCALE INVESTIGATION OF PERMEABILITY AND FLOW MODELING FOR HIGHLY STRESSED COALBED METHANE RESEROVIRS USING PULSE DECAY METHOD
… gas flow behavior of CBM reservoirs. The pulse-decay method (PDM) of permeability measurement is believed to be better suited for low-permeability rocks. In this study, application of the currently used pulse-decay laboratory permeability measurement techniques for highly stressed coals …
