A finite element based computational fluid dynamics (CFD) model was developed to study
the flow patterns within the slugs and mass transfer with and without superimposed chemical …

We present and analyze a modified Newton solver, the so called operator-related damped
Jacobian method, with a line search globalization for the solution of the strongly nonlinear …

Flux limiting for hyperbolic systems requires a careful generalization of the design principles
and algorithms introduced in the context of scalar conservation laws. In this chapter, we …

We present special finite element and multigrid techniques for solving prototypical cerebral
aneurysm hemodynamics problems numerically. An arbitrary Lagrangian–Eulerian (ALE) …

This is an experimental and numerical study of dry, frictional powder flows in the quasi-static
and intermediate regimes using the geometry of the Couette device. We measure normal …

Shearing wet granular systems causes a redistribution of the interstitial liquid, which can
affect the material's bulk behavior. Using the discrete-element method, we study the early …

[EN] Developing a numerical and algorithmic tool which correctly identifies unyielded
regions in yield stress fluid flow is a challenging task. Two approaches are commonly used …

Multiphase flows, including free surface and two-phase flows, are commonly encountered in
many industrial applications. Effects of wave phenomena are for example important when …

This note is concerned with the essential part of Finite Element Methods (FEM)
approximation of error analysis for quasi‐Newtonian modelling of thixo‐viscoplastic (TVP) …

In this thesis, we develop efficient numerical methods to solve the viscous-plastic sea ice
model on high resolution grids, with a cell size up to 2 km. This model describes the …
