  5. 5. A Lagrangian-Eulerian simulation framework for viscoelastic fluid flows

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

    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
