Dirk Ekelschot obtained his BSc. and MSc. at the faculty of Aerospace Engineering of Delft University of Technology.  In October 2010 he started his internship at the German Aerospace Center (DLR) site in Braunschweig, Germany. Research was performed on the field of wind tunnel acoustics for the Large Low Speed facility (LLF) in Marknesse, the Netherlands. His research was completed in the beginning of Januari 2011. His master thesis project was on the subject of hypersonic double compression ramp flow in the Hypersonic Test Facility Delft (HTFD) at the TU Delft. By using Quantitative Infrared Thermography (QIRT) and Tomographic Particle Image Velocimetry (PIV) the growth rate of longitudinal vortices over the double compression ramp at Mach = 7.5 is investigated and a three-dimensional impression of the velocity field is obtained.

The main objective of the current PhD thesis is the development of a goal-based error estimator using the adjoint approach for the Compressible Flow Solver in Nektar++. The main interest is on the methodology of solving for typical compressible flow problems, in this case using higher order h/p spectral element methods using the Discontinuous Galerkin (DG) formulation and the research and implementation of adaptive techniques applied to compressible flows. This includes the implementation of a p-adaptive algorithm in 2D and 3D and shock capturing techniques and later on, the posteriori error estimation technique using the adjoint formulation.
