Wave propagation in fluid containing solid particles with plugging phenomenon

Today, hydraulic transport of solid particles through pipelines is actively being pursued. The study of wave propagation in such a multiphase flow application is of prime importance for the determination of the shock wave induced, for example, by particle plugging in the system and is the subject of the present effort. The study included the experimental determination of the wave propagation velocity, the wave attenuation characteristics, and the reflected wave due to the presence of a discontinuity in a laboratory environment. The experimental results were found in good accord with those obtained analytically based on the one-dimensional wave propagation theory. A case study was conducted utilizing the analytical method to ascertain the pressure histories, wave attenuation, and reflected shock histories
