In this paper an attempt to provide a single degree of freedom lumped model for fluid structure interaction (FSI) dynamical analysis will be presented. The can used clarify some important concept in the FSI dynamics such as added mass, stiffness, damping, wave coupling ,influence mass coefficient and critical depth . numerical results show that natural frequency decrease with increasing many pa...

The main objective of this work is the development a Computational Fluid Dynamics model coupled with structural code for simulation and optimization fishing gears. As nets are highly deformable structures under influence incident water, use merely empirical correlations hydrodynamic forces, such as those used in many codes, does not provide precise predictions their behaviour. coupling between ...

We develop a mixed finite element method for the coupled problem arising in interaction between free fluid governed by Stokes equations and flow deformable porous medium modeled Biot system of poroelasticity. Mass conservation, balance stress, Beavers–Joseph–Saffman condition are imposed on interface. consider fully formulation based weakly symmetric stress-displacement-rotation elasticity Darc...
