PhD student (Applications in physical sciences)

Trondheim, Norway

I'm Norwegian, born and raised in Trondheim. I got my MSc in Physics in 2012 from the Norwegian University of Science and Technology (NTNU) in Trondheim. After graduating, I spent half a year working at SINTEF Energy Research before embarking on my PhD studies. My PhD work is part of the research project "Electrocoalescence III" which is conducted by SINTEF Energy Research and funded by the Norwegian Research Council, Statoil, Petrobras and Wärtsilä. The aim of my project is to use CFD modelling, in conjunction with experimental work performed by my colleagues, to provide insight into the physical processes that govern the electrocoalescence process. This process is employed both onshore and offshore to speed up the sedimentation of water drops in crude oil, such that the water forms a bulk phase in the bottom of a container and can be removed easily. Our hypothesis is that an improved understanding of the physical mechanisms will contribute towards reduced energy usage and more compact separation equipment.
