Abstract
The dynamic response of fluids in pipelines impacted by an external pulse loading with consideration of fluid-structural interaction effects was investigated. Two simple models to analyze the response of the fluid have been proposed. The simple models eliminate the need to solve the otherwise complicated fluid-structure interaction. The models predict the pressure magnitude and the pressure wave propagation through the pipeline. To verify the results from the simple models, finite element analyses with the ANSYS code considering fluid-structure interaction have been conducted. In the analyses, fluid-structure interaction effects 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.
