MSc THESIS STUDENT:  CFD - COMBUSTION

Your responsibilities:
In the event of overheating of the nuclear reactor core during a severe 
accident, large amount 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. CFD models for the prediction of this hydrogen combustion need further 
development and validation. Within the frame of the MSc thesis project, the 
following activities are proposed:
1)	Literature review on hydrogen combustion modelling, in order to get 
familiar with the topic
2)	Learning the ANSYS-FLUENT CFD solver. NRG has developed and implemented 
dedicated combustion models in FLUENT using user defined functions for the 
transient hydrogen combustion.
3)	Further development and validation of the hydrogen combustion models 
4)	Preparation of the MSc thesis
                      

Your profile:
•	MSc student in applied science, with specialization in computational 
fluid mechanics
•	Good knowledge of turbulence modelling 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
•	Housing and transportation for the period of stay
