1. Stable High-Order Finite Difference Methods for Aerodynamics
Sammanfattning : In this thesis, the numerical solution of time-dependent partial differential equations (PDE) is studied. In particular high-order finite difference methods on Summation-by-parts (SBP) form are analysed and applied to model problems as well as the PDEs governing aerodynamics. LÄS MER
2. Finite Difference Methods for Time-Dependent Wave Propagation Problems
Sammanfattning : Wave propagation models are essential in many fields of physics, such as acoustics, electromagnetics, and quantum mechanics. Mathematically, waves can be described by partial differential equations (PDEs). In most cases, exact solutions to wave-dominated PDEs are nearly impossible to derive. LÄS MER
3. High Order Finite Difference Methods with Artificial Boundary Treatment in Quantum Dynamics
Sammanfattning : The investigation of the dynamics of chemical reactions, both from the theoretical and experimental side, has drawn an increasing interest since Ahmed H. Zewail was awarded the 1999 Nobel Prize in Chemistry for his work on femtochemistry. LÄS MER
