During my time at Caltech in Prof. Chiara Daraio's group, I was excited to work on a project where we incorporated shape memory polymers into multi-stable mechanical structures to realize complex temperature responsive behavior. This concept could be applied to engineer adaptive structures that recognize changes in temperature and transform their shape in response, for example to make a greenhouse where the roof opens when the sun comes out. I couldn't have done it without Giada Risso! Thanks so much for being an amazing collaborator. Check out the article published today in Advanced Science here: https://lnkd.in/gpDjap4f

I'm excited to share that our paper for the Combustion Symposium in Milan is out. --> Talk is on Tuesday 10:00 in Turbulent Flames Session <-- We investigated thermodiffusive instabilities in turbulent lean hydrogen flames via DNS in realistic slot burner configurations. These instabilities have a leading order effect on the turbulent flame speed and their interactions with turbulence need to be better understood - for this, we varied the Karlovitz number. A movie of one DNS case is shown below. A decomposition of the turbulent flame speed shows that with an increase of Karlovitz number flame wrinkling reduces, but local flame propagation (stretch factor) increases - both important aspects for modeling! Gratitude to my co-authors Antonio Attili, Michael Gauding, and Heinz Pitsch for their great contribution to this joint work. If you are interested in hydrogen combustion and how the flame morphology and turbulent flame speed behave with Karlovitz number, join me at my talk on Tuesday 10:00 in the Turbulent Flames Session (Talk 2D02).

🚀 Thrilled to share that our paper has been published in IEEE Access 2024! 📚 Titled "Modeling of Inductances Considering Bar Harmonics and Temperature to Accurately Predict Output Torque of an Induction Motor", this research represents a significant step in refining the performance modeling of induction motors. 🔧 Traditional modeling approaches often overlook the impacts of harmonic fields, skin effect, and temperature on equivalent circuit parameters. Our work introduces an improved method that comprehensively includes: Total harmonic distortion in the magnetomotive force using a power function-based formulation. Combined effects of iron saturation, temperature, and skin effect on rotor leakage inductance and bar resistance. Consideration of rotor tooth-bridge permeance, enhancing the modeling accuracy. The effectiveness of our approach is validated through simulations and experiments on a 13 kW three-phase induction motor prototype, showing improved torque predictions across a wide operational range. 🌍 With the global push for net-zero carbon emissions and the rise of electric vehicles, accurately predicting motor performance is crucial. This method provides a deeper performance analysis for traction motors, paving the way for more reliable, high-speed EV traction designs. A huge shout-out to my amazing co-authors and the Charge Lab team for their hard work and dedication! 🔗 Read more on IEEE Access: https://lnkd.in/giE_4f-g Cheers!

Exciting insight into the world of additive manufacturing of graded materials! At our fourth scientific colloquium, we were able to experience an impressive presentation on the topic of “Graded materials produced using additive manufacturing: From process to properties”. It was fascinating to see the possibilities that additive manufacturing now offers to influence material properties locally in a targeted manner. The contents on - combinations of materials with different chemical compositions and - intended production and control of pores were particularly inspiring. Valuable input for our Collaborative Research Center and further research in this exciting field! 🙌 Many thanks to Prof. Niendorf and Dr. Wegener from the Institut für Werkstofftechnik IfW (Universität Kassel) for the excellent presentation and to Prof. Beck for the organization. We are already looking forward to the next colloquium in February, where Prof. Alexander Hasse will talk about adaptive structures.
