1. Summation-by-Parts Operators for High Order Finite Difference Methods
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : High order accurate finite difference methods for hyperbolic and parabolic initial boundary value problems (IBVPs) are considered. Particular focus is on time dependent wave propagating problems in complex domains. Typical applications are acoustic and electromagnetic wave propagation and fluid dynamics. READ MORE

3. Stable High-Order Finite Difference Methods for Aerodynamics
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : 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. READ MORE

5. Adjoint-based aerodynamic shape optimization
University dissertation from Uppsala UniversityAbstract : An adjoint system of the Euler equations of gas dynamics is derived in order to solve aerodynamic shape optimization problems with gradient-based methods. The derivation is based on the fully discrete flow model and involves differentiation and transposition of the system of equations obtained by an unstructured and node-centered finite-volume discretization.
