1. A Novel Immersed-Boundary Method for Multiple Moving and Interacting Bodies
Abstract : This thesis describes the development, implementation and validation of an implicit, second order accurate, finite-volume and instationary immersed-boundary method for simulating the detailed flow around multiple arbitrary moving and interacting bodies. The potential for flows including moving bodies or boundaries, such as multiphase flows still has to be fully realized. READ MORE

2. On boundary value problems for intracellular subdiffusion and signaling pathways, and for geometric flows
Abstract : The main part of this thesis concerns mathematical models for diffusion of proteins inside cells, including reactions between the proteins. Initially, such models are applied to describe signaling pathways in yeast cells, and the properties of the model are studied, especially in relation to models that do not include diffusion.

3. The Mirroring Immersed Boundary Method - Modeling Fluids with Moving and Interacting Bodies
Abstract : The detailed fluid flow around arbitrary, moving, interacting and deforming bodies is both complex and poorly understood and the commercial simulation tools simulating such flows are computationally to demanding. Hence, a new fast and accurate method for simulating complex multi-body flows is required. READ MORE

4. Boundary integral methods for Stokes flow : Quadrature techniques and fast Ewald methods
Abstract : Fluid phenomena dominated by viscous effects can, in many cases, be modeled by the Stokes equations. The boundary integral form of the Stokes equations reduces the number of degrees of freedom in a numerical discretization by reformulating the three-dimensional problem to two-dimensional integral equations to be discretized over the boundaries of the domain.

5. High Order Cut Finite Element Methods for Wave Equations
Abstract : This thesis considers wave propagation problems solved using finite element methods where a boundary or interface of the domain is not aligned with the computational mesh. Such methods are usually referred to as cut or immersed methods. READ MORE
