Application of MPS and FEM based Fluid-Structure Interaction Model to a Sequential Dam-Break Problem on Çoruh River
Öz
Studies about fluid-structure interaction (FSI)
problems do not have a long history. Fluid and structure has been separately modelled
with different formulations by researchers. However, studies about FSI are
limited and problems investigated in these studies are mostly out of civil
engineering areas. Problems such as dam-breaking, flood effect on structure,
slushing effect and tsunami are the problems consisting of a fluid structure
interaction in civil engineering. The present study, a fluid structure
interaction model is developed by using moving particle semi-implicit method
(MPS) and finite element method (FEM) for fluid and structure, respectively.
The developed code is applied to an idealized sequential dam-break problem. The
effect of failed upper dam on the lower dam body is investigated in terms of
pressure readings. Besides, behavior of flood in lower reservoir is observed
with given profiles of surface water. Both results can be used for future
studies and taking protective measures.
