The book aims to aid designers, researchers and postgraduate students of pipes conveying fluid in predicting their dynamic behaviour for various flow velocities, fluid pressures and initial tensions as well as varying geometric and material properties. It also aims to provide practically useful information of interactions between fluids and structures. Throughout,numerical results are carefully compared with experimental observations, and conclusions drawn as to the appropriateness and accuracy of the models used.
