7. 5. 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
