Last week I attended the ASME Turbo Expo in Rotterdam. I was lucky to open the first Combustion Dynamics session on Flame Transfer Functions as a session chair and to present my recent work „From Pressure Time Series Data to Flame Transfer Functions: A Framework for Perfectly-premixed Swirling Flames„. After a long while, this was an excellent occasion to meet colleagues and friends to discuss research and collaborations.
Isaac Boxx from the DLR in Stuttgart organized a workshop for his HYBURN project. I was asked to present on our collaborative work entitled „Pressure time series – A valuable data set for flame dynamics modeling„. The idea to identify a flame model based on pressure time series continued to grow and got accepted recently for the ASME Turbo Expo conference in Rotterdam.
We hosted 13 participants (between 12 and 14 years old) of the Girl’s Day 2022 at TU Berlin. Within our workshop ‚Clean Energy Generation‘, we discussed problems in energy generation and the link to combustion science. Additionally, we prepared around 10 experiments with candle flames, with which the participants could learn ‚hands-on‘ about flammability limits, emissions, ignition etc. We enjoyed the questions, the discussions and their curiosity about this topic and hope to have sparked some deep interest in this field.
My PhD students Mario Casel and Vikas Yadav have both received the acceptance letter for their submissions for the 39th International Symposium on Combustion. I am extremely happy to see their success !
I presented the plenary talk on „Machine Learning in Chemically Reacting Flows: Trends and Perspectives“ in Heidelberg. This national event was organized by Prof. Eva Gutheil and was my first in-person meeting since I started at TU Berlin.
My paper „From Pressure Time Series Data to Flame Transfer Functions: A Framework for Perfectly-premixed Swirling Flames“ was accepted for the ASME Turbo Expo Conference 2022 in Rotterdam. This work was done in collaboration with Alp Albayrak.
I will present my recent work on „Pressure data for parameter calibration of flame transfer function models for premixed swirling flames“ at the 30. Deutschen Flammentag. Xiaomin Wang, an exchange research trainee from Coria/Rouen worked on this topic for 4 month in our group at TU Berlin. I will also chair the „Combustion in Gas Turbines“ session. The conference will be held online and the registration is still open.
The DMF group submitted two papers to the SoTiC 2021 – Symposium on Thermoacoustics in Combustion: Industry meets Academia conference. Both papers will be presented on the 07. and 08.09. in the afternoon sessions.
The X-Student Research Group just presented on their outstanding research results. We are happy to have hosted these highly motivated students within our group. We will share their results on our TU webpage (as soon as we have access back to the IT services). Based on this very successful teaching experience, we will establish a follow-up student project for the upcoming winter term 2021/22.
New paper accepted !
Our latest work entitled „An Exceptional Point switches stability of a thermoacoustic experiment“ is accepted for publication in the Journal of Fluid Mechanics.
The DMF group is selected for the X-Student Research Group organized by the Berlin Univerity Alliance (16 grants out of 76 applications). We are happy to introduce Master students from all Berlin Universities to our specific research topics and to work with them during this summer.
I launched a new colloquium „Data-Driven Methods in Enginering Science“ at TU Berlin, which is open to researchers and engineers. Here, we will discuss applications and limitations of modern methods coming from Machine Learning/Artifical Intelligence. Today, we started with a talk from a member of my group. Further talks will be acounced at the DMF group webpage.
Yesterday, I was speaking in front of the Berlin International Graduate School in Model and Simulation based Research (BIMoS) audience. Thanks for the invitation, I enjoyed the discussion after the talk.
In the first and second week of March 2021, Master students can attend the two new courses developed at TUB: (i) OpenFoam for Combustion Processes and (ii) Machine Learning for Dynamical Systems, where each course is equivalent to 6 credit points (4 SWS).
The Berlin International Graduate School in Model and Simulation based Research (BIMoS) invited me to give a virtual seminar talk on the current research at the DMF group on 15th February 2021. Looking forward to meet new colleagues from TUB.
New paper online !
This paper published in the Journal of Engineering for Gas Turbines and Power reports on the collaboration with Dr. I. Boxx from DLR Stuttgart on a high-pressure combustor.
The last two weeks, I introduced two new courses at TU Berlin (i) OpenFoam for Combustion Processes and (ii) Machine Learning for Dynamical Systems. Although the current situation is challenging for everyone, we had positive and valuable feedback from the students.
The DAEDALUS collaboration voted new associated PIs and I am part of the group now. Together, we will focus on data-driven methods for life sciences and fluid dynamics.
I gave my first webinar talk at the Chair of Robotics, Artificial Intelligence and Embedded Systems (TUM). Thanks to Noah Klarmann for the invitation to talk about machine learning methods entering the field of combustion dynamics.
New paper online !

Good bye and save travel home to the ATHENS programme participants of March 2019 ! I really enjoyed this week having motivated and smart students around me. This hard working group did not even notice me taking a snapshot…
My proposed Mini-Symposium „Numerical modelling of combustion instabilities“ has been accepted for the 17th International Conference on Numerical Combustion. There will be in total 6 presentations given by colleagues from TU Berlin (Prof. Oberleithner), NTNU Trondheim (Prof. Moeck), ETH Zurich (Prof. Noiray), CentraleSupélec (Dr. Ducruix and Dr. Schmitt) and Cambridge (Dr. Magri). I will present my latest research on the impact of methane/hydrogen fuel mixtures on the intrinsic thermoacoustic feedback loop.
The course on Thermoacoustics modelling in the framework of the ATHENS programme just ended. I enjoyed having 18 students from all across Europe during this week in the computer lab. Teaching works best, when students motivate each other. Here is the proof:
My colleague Thomas Steinbacher just published a new paper on flame dynamics. It can be downloaded here.
I just came back from the 37th International Symposium on Combustion at Dublin/Ireland. Besides co-chairing a „Gas Turbine“ session, I presented a poster with work in progress. If you could not see it during the poster session, take a look at it here.
The thermoacoustic course that I will give in the framework of the ATHENS programme is now online and registrations are open !
The one week course will provide a basic understanding of numerical modelling of thermoacoustic instabilities together with hands-on sessions in the afternoons. Feel free to join !
It is an honor and pleasure to serve as a session chair for the 37th International Symposium on Combustion organized by Profs. Heinz Pitsch (RWTH Aachen) and Hai Wang (Stanford University). See you at the Tuesday morning „Gas Turbine“ session !
I just started a new project: my personal research webpage.
