The aim of the present research is to identify, describe and quantify the principal mechanic-hydraulic relationships during hydraulic transients in pressurized pipe flows in view of improving pipe design and reduce pipe and system failure. Phenomena affect ...

The paper presents the analysis of the effect of Fluid-Structure Interaction (FSI) occurring during hydraulic transients in pipe coils, in particular the main developments and findings. The research work comprises the development of mathematical models, th ...

The paper presents the analysis of fluid–structure interaction occurring during hydraulic transients in pipe coils by means of a four-equation model. The purpose is to understand and describe the effect of the coil movement on the transient wave. The four- ...

This investigation aims at assessing the fluid-structure interaction (FSI) occurring during hydraulic transients in straight pipeline systems fixed to anchor blocks. A two mode 4-equation model is implemented incorporating the main interacting mechanisms: ...

The present paper approaches fluid-structure interaction by means of a 4-equation model. Experimental data collected from a straight copper pipe-rig lying directly on the lab floor is used for the model validation in terms of wave shape, timing and damping ...

Floodplains are regions of great interest for environmental assessment as they constitute important ecological reserves and contribute efficiently to natural flood attenuation. However, the implementation of a model describing the basic hydrological behavi ...

Transient pressure waves in real pipe systems are affected by several phenomena not accounted for in the classic waterhammer theory. Damping mechanisms are differently manifested according to the material, configuration and existing features of pipe system ...

This research aims to enhance the knowledge on stress–strain states of a coiled pipe used for Hydraulic transient experiments. The membrane theory of shells of revolution has been applied for the description of axial and circumferential strains while an in ...
