✦ Synopsis

The dynamic response of #uids in pipelines impacted by an external pulse loading with consideration of #uid}structural interaction e!ects was investigated. Two simple models to analyze the response of the #uid have been proposed. The simple models eliminate the need to solve the otherwise complicated #uid}structure interaction. The models predict the pressure magnitude and the pressure wave propagation through the pipeline. To verify the results from the simple models, "nite element analyses with the ANSYS code considering #uid}structure interaction have been conducted. In the analyses, #uid}structure interaction e!ects have been considered by employing direct coupling elements. A comparison between the results from the simple models and the ANSYS analyses has been conducted. The simple models are shown to provide an easy way to estimate the pressure.
