As an exchange PhD student from the University of Belgrade, I want to tell you of my short stay at the NTNU – Norwegian University of Science and Technology in Trondheim. It is a story about climate change and NOx, developing models, and meeting new people.
How come I ended up here?
I had a short research stay connected to a programme which aims to contribute to economic growth and social development through co-operation in higher education and research in the Western Balkans. You can read more about the HERD/Energy programme that NTNU administers here.
Who am I?
Exchange PhD student, Ivana Čeković, University of Belgrade, Faculty of Mechanical Engineering.
What have I been doing?
I have been working on a project related to modelling of thermal conversion of biomass. There was a special emphasis on conversion of nitrogen in the fuel to NOx.
My personal motivation for this?
We all live under different clouds, but the same sky. Taking care of our planet, Earth, is important. We must focus on emissions of pollutants causing global warming and climate change.
If we cannot stop it, how to put it under control?
Renewable energy sources instead of fossil fuels are providing CO2-neutrality, but still there are NOx emissions which means production of acid rain precursors and greenhouse gases.
What are we going to do about it?
We need to research formation of NOx. There are two sources of NOx in the combustion processes: N2 from the air and nitrogen from the fuel. We have too little knowledge about the fuel-nitrogen conversion.
What have I been working on?
Demolition wood combustion. I have been modelling nitrogen conversion in commercial software LOGEsoft instead of experiment or CFD, to provide lower costs and less CPU time.
Did I make a progress in model development?
For good results you need time. A lot of reading, going deeper into equations, understanding the processes and working in software, but I think that I am on the right path.
Did I meet new people?
Of course, that is the most important part of my research stay. My stay would have been the same without my colleagues here at NTNU. They helped me a lot! Some of them became my closest friends. And I have to admit that I am sad because I have to leave Norway for a while. I love my friends, I love Norway! NTNU is a great university! And I made really important career steps here.
What was all this running about?
The best part of my stay here was joining the team in the 4 day long run St. Olavsloppet. I am so happy I was a part of the NTNU team. “All for one – one for all” spirit. Running and supporting team members. Making food together. Laughing a lot. Scandinavia is beautiful. I received my first medal ever. Connecting with people is so nice. Discussing scientific topics. Giving advices to each other. Planning new meetings. Choosing places to travel together.
Finally, some advice to myself and to you all:
When something comes to an end, it is really a new fresh beginning. Remember to have a positive attitude. Be patient… Try to help people as much as you can. Be kind and friendly. Research. Make a balance. Keep smiling.
