Unified lagrangian formulation for elastic solids and incompressible fluids. application to fluid-structure interaction problems via the PFEM
(Elsevier Science Sa, 2008-03)
We present a general Lagrangian formulation for treating elastic solids and quasi/fully incompressible fluids in a unified form. The formulation allows to treat solid and fluid subdomains in a unified manner in fluid–structure ...
An Improved Immersed-Boundary Algorithm for Fluid-Solid Interaction un Lattice-Boltzmann Simulations
(Planta Piloto de Ingeniería Química, 2013-08)
An improved algorithm combining the features of the lattice Boltzmann and the immersed-boundary methods is presented. Following previous formulations, the method represents a fluid con-strained by flexible boundaries by ...
Fluid–structure interaction study of the start-up of a rocket engine nozzle.
(Pergamon-elsevier Science Ltd, 2010-04)
The aim of this paper is to analyze the aeroelastic processes developed during the starting phase of a rocket engine via a coupling fluid/structure code. This analysis gives a better understanding of the behavior of the ...

Study of the state a Francis turbine
(Politechnika Gdanska, Wydzial Oceanotechniki i Okretownictwa, 2013-04-01)
This paper presents a methodology to evaluate the technical state of a Francis turbine by shaft rotor dynamic simulation. There are several rotor dynamic criteria that define the technical state of a turbo-machine. To feed ...
A unified symmetrical formulation for interactions between elastic solids and incompressible fluids
(CIMNE, 2007)
Variational methods have long been a fundamental tool in the development of mathematical physics. This is a particularly true in the field of mechanics, where they allow physical and geometrical features of the problem in ...
Fluid-Structure Interaction Using the Particle Finite Element Method
(Elsevier Science Sa, 2006-12)
In the present work a new approach to solve fluid–structure interaction problems is described. Both, the equations of motion for fluids and for solids have been approximated using a material (Lagrangian) formulation. To ...
