  2. 11. Numerical Modeling of Turbulent Gas-Particle Flow

    Author : Aldo Benavides; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence modulation.; kinetic theory; Eulerian-Eulerian model;

    Abstract : This work presents a theoretical and numerical study of gas-particle two-phase flow within the Eulerian framework. Although gas-particle flows have been extensively studied, there is still no general agreement on the constitutive equations for an Eulerian-Eulerian model in which the dispersed phase is treated as a continuum, i.e. a granular fluid.

  4. 12. On the Arbitrary Lagrangian-Eulerian Finite Element Method

    Author : Lars Olovsson; Kenneth Runesson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; large deformation plasticity; FEM; ALE; multi-material Euler; machining simulations;

    Abstract : This thesis has been devoted to the study and development of algorithms for Finite Element (FE) simulations of mechanical processes involving large deformations. Aspects of three different formulations have been considered:(i) The single material Arbitrary Lagrangian-Eulerian (ALE) formulation is a method where the FE mesh is allowed to move independently to the material flow.

    Author : Andreas Söderström; Ken Museth; Matts Karlsson; Jos Stam; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis focuses on improving and extending the available toolset for Eulerian, i.e. grid based, free surface fluid animation and level set based surface tracking in the context of computer graphics and visual effects. READ MORE

  6. 14. Simulation of consolidation processes by eulerian two-fluid models

    Author : Katarina Gustavsson; KTH; []
    Keywords : ;

    Abstract : The objective of this report is to study a model of agravity and shear induced consolidation process of a dense,flocculated suspension.The suspension is modeled as a two-constituent mixture of afluid and solid particles by an Eulerian two-phase fluid model. READ MORE

  7. 15. A Lagrangian-Eulerian simulation framework for viscoelastic fluid flows

    Author : Simon Ingelsten; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational Fluid Dynamics; non-Newtonian flow; Immersed boundary methods;

    Abstract : Viscoelastic fluids appear in various industrial applications, including adhesive application, additive manufacturing, seam sealing and parts assembly with adhesive. These processes are characterized by complex geometry, moving objects and transient multiphase flow, making them inherently difficult to simulate numerically. READ MORE
