New colleagues at STFS

Over the coming months, several PhD candidates (Philipp Koob, Bich-Diep Nguyen, Driss Kaddar, Tim Jeremy Patrick Karpowski, Jannis Reusch) will complete their theses, while new researchers have joined Simulation of Reactive Thermo-Fluid Systems (STFS), TU Darmstadt. What makes me especially happy is that each of them joined through long-standing, trusted collaborations — each following a unique path.

Postdoc position at STFS

Topic: Hot-gas / cooling-air interaction in non-reactive flows over film-cooled turbine nozzle guide vanes (NGVs). See attached images.

Excursion to industrial partner Rolls-Royce

As part of our University Technology Centre (UTC) partnership with Rolls-Royce, we recently took 15 Bachelor students on a two-day excursion to Rolls-Royce Dahlewitz — a truly unique opportunity to witness jet-engine assembly and testing up close.

International Conference on Numerical Combustion (ICNC)

The International Conference on Numerical Combustion (ICNC) is one of the true highlights in my calendar every two years. The program is focused, the discussions stimulating and purposeful — three days that feel like a big family reunion of the combustion community.

STFS and RSM Team

It is a long-standing tradition that our institute Simulation of Reactive Thermo-Fluid Systems (STFS), TU Darmstadt, together with Reaktive Strömungen und Messtechnik (RSM), TU Darmstadt, led by Andreas Dreizler, holds a one-week retreat in the Darmstädter Haus in Kleinwalsertal.

Lecture re-designed

Right before the new semester kicks off — with our completely redesigned course Chemically Reactive Flows – Theory and Practice with Python [1] — a quote on my coffee mug caught my attention (see pictures [2]):

A milestone that makes me truly proud as a mentor

A major milestone on this path is an ERC Starting Grant. Congratulations to Arne Scholtissek for being awarded the ERC Starting Grant “Protocol for data-driven Manifold generation, validation, and utilization in high-fidelity combustion simulations – ProtoMan”.

(or why thinking inside a box can be key to getting out of it)

It was a pleasure to welcome Thomas Howarth from the Institute for Combustion Technology, RWTH Aachen University, to Darmstadt. His talk Lean Premixed Hydrogen Flames: From Laminar Foundations to Turbulent Jets sparked lively discussions.

(What are Transfer Projects? Why are they important? What’s our topic?)

German Research Foundation has approved my Transfer Project “Modelling of Flow–Flame–Cooling-Air Interaction under Technically Relevant Conditions”. The project is now part of the Collaborative Research Centre / Transregio 150 “Turbulent, Chemically Reacting Multiphase Flows Near Walls” (speaker: Andreas Dreizler) of Technische Universität Darmstadt and Karlsruher Institut für Technologie (KIT).

Thermodynamics Lecture

Today's Thermodynamics Lecture Ended with a Heroic Question What would Captain America (or Tux as a Marvel hero) say if a hydrogen flame hit his shield?
