چکیده
Fig. 1. Plot of the magnitude of the velocity (upper left) and axial component (x-direction) of the stress (upper right) of a steady viscoelastic fluid flow in a simple planar channel with an enlargement (motivated by a simple model of a small arterial aneurysm). This component of the stress is the most pronounced at the entrance and exit of the enlargement. The magnitude of the shear stress (center) of the viscoelastic fluid along the upper wall is significantly different than that of a Newtonian fluid, despite having an almost identical velocity field.

Presenting a Modified SPH Algorithm for Numerical Studies of Fluid-Structure Interaction Problems
A modified Smoothed Particle Hydrodynamics (SPH) method is proposed for fluid-structure interaction (FSI) problems especially, in cases which FSI is combined with solid-rigid contacts. In current work, the modification of the utilized SPH concerns on removing the artificial viscosities and the artificial stresses (which such terms are commonly used to eliminate the effects of tensile and numeri...

Fluid-structure interaction (FSI) occurs when the dynamic water hammer forces; cause vibrations in the pipe wall. FSI in pipe systems due to Poisson and junction coupling has been the center of attention in recent years. It causes fluctuations in pressure heads and vibrations in the pipe wall. The governing equations of this phenomenon include a system of first order hyperbolic partial differen...

In this paper, modal analysis of the fluid-structure interaction has been investigated. Using classical laminated plate theory, a closed form solution for natural frequencies of FSI is extracted. For fluid, homogenous, inviscid and irrotational fluid flow is assumed. Then, a combined governing equation for the plate-fluid system is derived. In order to validate the equations and results, they a...
