I put this wiki up to have an online repository for all my research-related work. And perhaps others can find some gain in it also. These documents include presentations, posters, papers, and whatever else I find important. Mostly these files concern my PhD work on thermoacoustics, but there's some other stuff as well.

Research
Posters:


 * Weakly non-linear thermoacoustics for general porous media

Poster I presented on the 2008 Burgersday in Delft. It gives an introduction into thermoacoustics and some of my first results on the analysis of standing-wave thermoacoustic devices.


 * Modeling of a traveling-wave prime mover

Poster I presented on the Acoustics'08 conference in Paris. It shows some of my results on modelling and simulation of a traveling-wave prime mover.

Presentations:


 * Thermoacoustic Devices: oscillatory gas flow with heat transfer to solid boundaries

Talk on thermoacoustic devices, given at the 2009 Burgersday in Eindhoven.


 * Thermoacoustic Devices

Seminar on thermoacoustic devices, given at the Royal University of Technology, in Stockholm Sweden, 5th November 2008.


 * Elliptic Variational Inequalities

Fifth CASA-seminar on free and moving boundary value problems, 16 April 2008.
 * Fluid Mechanics

Fifth CASA-seminar on continuum mechanics, 3th May 2006.
 * Iterative techniques for solving eigenvalue problems

Third CASA-seminar on eigenvalue problems, 9th November 2005.

Other reports:


 * Calculations of the acoustic end correction of a semi-infinite circular pipe issuing a subsonic cold or hot jet with co-flow

Report of my internship at the Royal Institute of Technology (KTH) in Stockholm, Sweden. A matlab code is developed to calculate the acoustic end correction and the complex-valued reflection coefficient for arbitrary modes.

Master's thesis work in which a model is derived for the rechargeable Li-ion battery. The model is based on a mathematical description of the physical processs occurring inside the battery. The resulting problem is solved using perturbation methods and validated using numerical results.
 * Li-ion battery modelling
