LocationNetherlands, Petten
InternationalYes, international applications are welcome
Closure DateFriday, October 01, 2021
NRG is the sole nuclear service provider in the Netherlands. Our customers include 
major international companies. Our motive is to ensure a renewable energy supply, 
a cleaner environment and better health. Our business is to provide specialised, 
technical services in the areas of risk, safety and optimisation of business 
operations in the nuclear, oil and gas and petrochemical sectors. We are leaders 
in the field of Nuclear Data analysis for research and innovation for many nuclear 
applications. Further international development is one of our key ambitions. Our 
offices are located in Arnhem and Petten. The team is based in Petten.

Within our unit Research and Innovation, we are currently seeking for a  


Your responsibilities:
In the event of overheating of the nuclear reactor core during a severe accident, 
large amounts of hydrogen are generated that may be released into containment 
building. As the hydrogen mixes with air in the containment, it can form a 
flammable gas mixture. The possible combustion of hydrogen may damage relevant 
safety systems and may put the integrity of the containment 
building at risk. Due to the increasing potential of CFD, especially in terms of 
reduced costs and risks when compared to experimental studies, great efforts have 
been put on the improvement of current CFD models. However, CFD approaches for the 
prediction of turbulent  hydrogen combustion need further development and 
validation, as they are required to properly reproduce the main physical aspects 
under different regimes (such as deflagration and detonation) and different 
conditions of turbulent hydrogen combustion. 
Within the frame of the MSc thesis project, the following activities are proposed:

1) Literature review on turbulent combustion modelling, in order to get familiar 
with the topic.

2) Learning the and OpenFOAM CFD solvers. NRG has developed and implemented 
dedicated combustion models in OpenFOAM for the transient hydrogen turbulent 

3) Implementation of a density based version of the current combustion model (TFC) 
in OpenFOAM for fast deflagration problems.

4) Investigation and implementation of specific convective schemes for improving 
the accuracy of the combustion model (i.e. pressure wave phenomena).

5) Application of the combustion models to different experimental studies for 
validation purposes. 

6) Further development and validation of the hydrogen combustion models, in the 
context of non-uniform mixture deflagrations (in presence of steam, CO, etc.).
7) Preparation of the MSc thesis.                

Your profile:
•	MSc student in applied science, with specialization in computational fluid 
•	Good knowledge of fluid mechanics and numerical methods
•	Required computer experience: Linux, Windows,  C/C++
•	Fluency in written and spoken English
•	Good analytical and problem solving skills
•	Dedicated, good communication and social skills

Our offer:
•	A challenging thesis project to be executed within a successful team with 
an informal atmosphere and an excellent reputation
•	Strong support from enthusiastic members of the CFD team 
•	Monthly allowance/stipend
•	Transportation for the period of stay

For security clearance, only European citizens will be considered (or non-
Europeans currently enrolled in a Dutch university).
