Background and activities
1. Area of work
My PhD project forms part of a EU funded project, NanoSim, where a multi-scale modelling approach is followed to develop an industrial scale, fluidized bed CLC (chemical looping combustion) reactor. The CLC concept aims to produce energy from fossil fuels, while producing a separate, pure CO2 stream. My part of the project will focus on the modelling of the reactive flow in the industrial fluidized bed. A filtered modelling approach is used to achieve reasonable computational times. In this approach the effect of the sub-grid scale solid structures is modelled by asjustments to the drag law, mass and heat transfer rates etc.
2. Skills and expertise
My main field of experitise is computational fluid dynamics, primarily using FLUENT. During previous work on fluidized beds I focused specifically on Eulerian-Eulerian granular flow modelling and on the DDPM (dense discrete phase model) in FLUENT
I completed my Bachelor's in Chemical Engineering at the University of Stellenbosch in South Africa. Afterwards I achieved a Master's at the same institute for a study investigating the flow behaviour in a steelmaking tundish.
Following my studies in South Africa I moved to Norway where I worked for SINTEF Materials and Chemistry for a short period. Here I specialized in the flow modelling of fluidized beds using different modelling methods. After gaining some experience in the field I enrolled for a PhD at NTNU on a related topic.
4. Other interests
I like to spend my free time playing guitar, mountain biking and doing landscape photography.
