Finite Element Analysis in Fluid Dynamics

Finite Element Analysis of Compressor Valve Dynamics

Web dynamics analysis using finite element simulations

This work focuses on web dynamics and wrinkles analysis in industrial web handling systems by using finite element modeling. The main objective is to simulate wrinkles in a real environment with the control part of the system, depending on mechanical parameters and process data. The effects of misaligned rollers and a roller deflection are specifically analyzed in order to study the influence o...

Wall stress and flow dynamics in abdominal aortic aneurysms: finite element analysis vs. fluid-structure interaction.

Abdominal aortic aneurysm (AAA) rupture is the clinical manifestation of an induced force exceeding the resistance provided by the strength of the arterial wall. This force is most frequently assumed to be the product of a uniform luminal pressure acting along the diseased wall. However fluid dynamics is a known contributor to the pathogenesis of AAAs, and the dynamic interaction of blood flow ...

Lagrangian Finite Element Analysis of Newtonian Fluid Flows

A fully Lagrangian nite element method for the analysis of Newtonian ows is developed. The approach furnishes, in e ect, a Lagrangian implementation of the compressible Navier–Stokes equations. As the ow proceeds, the mesh is maintained undistorted through continuous and adaptive remeshing of the uid mass. The principal advantage of the present approach lies in the treatment of boundary conditi...

Eigenproblems from Finite Element Analysis of Fluid-structure Interactions

We present two methods for calculating resonant frequencies and mode shapes for fluid-structure vibration problems. We model the fluid-structure interaction problem using the #-V-P, finite element technique. This eigenproblem is more complicated than for ordinary structural analyses, as the formulation produces a quadratic eigenproblem (similar to those for gyroscopic systems). We derive proper...
