Simulation of viscoelastic squeeze flows for adhesive joining applications

Efficient simulation of nonlinear viscoelastic fluid flows

This paper presents a new and efficient method for computing the flow of a non-Newtonian fluid. The approach is based on two independent concepts: Time-dependent simulation of viscoelastic flow: A new decoupled algorithm, presented in P. Saramito, Simulation numerique d'ecoulements de fluides viscoelastiques par eRments finis incompressibles et une methode de directions alternees; applications,...

Lattice Boltzmann Method for the Simulation of Viscoelastic Fluid Flows

The simulation of flows of viscoelastic fluids is a very challenging domain from the theoretical as well as the numerical modelling point of view. In particular, all the existing methods have failed to solve the high Weissenberg number problem (HWNP). It is therefore clear that new tools are necessary. In this thesis we propose to tackle the problem of the simulation of viscoelastic fluids pres...

Numerical simulation of 3D viscoelastic flows with free surfaces

Adhesive interactions of viscoelastic spheres

We develop an analytical theory of adhesive interaction of viscoelastic spheres in quasistatic approximation. Deformations and deformation rates are assumed to be small, which allows for the application of the Hertz contact theory, modified to account for viscoelastic forces. The adhesion interactions are described by the Johnson, Kendall, and Roberts theory. Using the quasistatic approximation...

Stabilisation Techniques for Viscoelastic Flows

In a comparative study, three di erent procedures of stabilisation techniques are considered for incompressible viscoelastic ow. The standard benchmark of ow past a sphere falling in a cylindrical vessel is employed to test these stabilisation techniques. First, discontinuity capturing (for stress) has been employed to investigate stabilisation properties. Then, the Zienkiewicz Zhu (ZPR-Q) quad...
