    In this work, the Immersed Boundary Method (IBM) is adapted and implemented in the context of Smoothed Particle Hydrodynamics (SPH) method to study moving solid bodies in an incompressible fluid flow. The proposed computational ...
  • Dynamic refinement for fluid flow simulations with SPH 

    Reyes López, Yaidel; Roose, Dirk (2011)
    Text en actes de congrés
    Accés obert
    In this paper, we present a dynamic refinement algorithm for the SPH method where a particle is refined by replacing it with smaller daughter particles. The position of the new particles is calculated by using a square pattern ...

    Crespo, A.J.C.; Domínguez, J.M.; Valdez-Balderas, D.; Rogers, B.D.; Gómez-Gesteira, M. (2011)
    Text en actes de congrés
    Accés obert
    Smoothed Particle Hydrodynamics (SPH) is a powerful technique used to simulate complex free-surface flows. However one of the main drawbacks of this method is the expensive computational runtime and the large number of ...

    Text en actes de congrés
    Accés obert
    Particle methods have become indispensible in conformation dynamics to compute transition rates in protein folding, binding processes and molecular design, to mention a few. Conformation dynamics requires at a decomposition ...
  • Molecular-dynamics investigation of nanoburnishing process 

    Kuznetsov, Viktor P.; Nikonov, Antony Y.; Dmitriev, Andrey I. (2011)
    Text en actes de congrés
    Accés obert
    It is well known that the burnishing process affects the surface characteristic, namely: surface roughness, surface hardness, wear resistance, fatigue resistance and increased maximum residual stress in compression. ...
  • Smoothed particle hydrodynamics simulation of nonspherical particle suspensions 

    Polfer, Pit; Wonisch, Andreas; Kraft, Torsten (2011)
    Text en actes de congrés
    Accés obert
    Particulate suspensions are used in many technical areas: ceramic processing, powder metallurgy and pharmaceutical applications being only a few examples. In many of these applications the microstructure determines the ...
  • Permeability assessment of heterogeneous porous media using the Lattice Boltzmann method 

    Jones, B.; Feng, Y.T. (2011)
    Text en actes de congrés
    Accés obert
    Material characterisation is one of the most important aspects of accurate numerical modelling; correct material properties must be obtained for the correct behaviour to be observed. Traditionally permeability is measured ...
  • Numerical simulation of oil leakage, water flooding and damaged stability of oil carrier based on moving particle semi-implicit (MPS) method 

    Cheng, Liang-Yee; Gomes, Diogo V.; Yoshino, Adriano M.; Nishimoto, Kazuo (2011)
    Text en actes de congrés
    Accés obert
    Oil leakage or water flooding in a damaged oil carrier are complex phenomena that involve fluid-solid interaction with complicated geometry and multiphase flow. In order to assess the damaged stability and environmental ...
  • Numerical investigation of three-phase flows using incompressible smoothed particle hydrodynamics 

    Zainali, Amir; Tofighi, Nima; Yildiz, Mehmet (2011)
    Text en actes de congrés
    Accés obert
    An ISPH method for the simulation of three-phase flows is presented in this article. The proposed method is investigated through the simulation of a droplet located at the interface of two immiscible fluids as well as diamond ...
