2. Weak Boundary and Interface Procedures for Wave and Flow Problems
Sammanfattning : In this thesis, we have analyzed the accuracy and stability aspects of weak boundary and interface conditions (WBCs) for high order finite difference methods on Summations-By-Parts (SBP) form. The numerical technique has been applied to wave propagation and flow problems. LÄS MER
3. Vortex generators and turbulent boundary layer separation control
Sammanfattning : Boundary layer separation is usually an unwanted phenomenon in most technical applications as for instance on airplane wings, on ground vehicles and in internal flows such as diffusers. If separation occurs it leads to loss of lift, higher drag and results in energy losses. LÄS MER
4. On the Arbitrary Lagrangian-Eulerian Finite Element Method
Sammanfattning : This thesis has been devoted to the study and development of algorithms for Finite Element (FE) simulations of mechanical processes involving large deformations. Aspects of three different formulations have been considered:(i) The single material Arbitrary Lagrangian-Eulerian (ALE) formulation is a method where the FE mesh is allowed to move independently to the material flow.

5. Radial basis function methods for pricing multi-asset options
Sammanfattning : The price of an option can under some assumptions be determined by the solution of the Black–Scholes partial differential equation. Often options are issued on more than one asset. In this case it turns out that the option price is governed by the multi-dimensional version of the Black–Scholes equation. LÄS MER
