Constraint Penalization Method in the Lattice Boltzmann Method (LBM) for Fluid-Structure Interaction
Tristan Millet, Erwan Liberge
A constraint penalization method is introduced within the Lattice Boltzmann (LBM) framework to model fluid-structure interactions involving rigid bodies. The proposed approach exte…
Total variations reduction for an exact control applied to a dynamical mechanical system
Philippe Destuynder, Erwan Liberge
In an optimal control strategy, an important point is to define the cost of the control. Usually it is added to the control criterion and multiplied by a small coefficient denoted…
About fluid forces computation for Volume Penalization coupled with Lattice Boltzmann method (VP-LBM)
E. Liberge, C. Béghein
In this paper, two different approaches fluid forces computation approaches are compared in the frame of Volume Penalization - Lattice Boltzmann Method (VP-LBM). The first method,…
About penalty-duality methods in fluid-structure interactions
Philippe Destuynder, Erwan Liberge
In fluid-structure interaction problems, some people use a penalty method for positioning the structure inside the fluid. This is usually performed by considering that the fluid is…
Lattice Boltzmann Method for Fluid-Structure Interaction with incompressible NeoHookean materials in small perturbations
Sébastien Mey, Erwan Liberge, Claudine Béghein
This paper deals with the numerical modelling of the interaction between a fluid and an incompressible solid (Neo Hookean) in small perturbations with the lattice Boltzmann method…
Fluid Structure Interaction modelling using Lattice Boltzmann and Volume Penalization method
Erwan Liberge, Claudine Béghein
This paper proposes an approach combining the Volume Penalization (VP) and the the Lattice Boltzmann method (LBM) to compute fluid structure interaction involving rigid bodies. The…
A volume penalization lattice Boltzmann method for simulating flows in the presence of obstacles
M. Benamour, E. Liberge, C. Béghein
The LBM is combined with the Volume Penalization (VP LBM) approach to simulate flows in the presence of obstacles. The single relaxation time LBM and the multiple relaxation time L…
