The Open Access article is available here: https://lnkd.in/eTf_b69t This work was performed in close collaboration with Yuriy Shoshin, Thijs Hazenberg, XiaoCheng Mi, Jeroen van Oijen and Philip De Goey at Thermo-Fluids Engineering (TFE) at TU Eindhoven

I'm excited to announce our recent article "Nitric oxide laser-induced fluorescence using the fifth harmonic of a broad-band Nd:YAG laser", published in Applied Physics B. The article is open-access and available online now through the link in the comment below. What originated from the question: "Could there be something we can do in our lab with a 5th harmonic generator?" led to the hypothesis that it could potentially work well for the detection of nitric oxides. Spoiler: it works indeed in several conditions, including high temperatures and pressures, and gives rise to interesting multi-photon absorption features at higher fluences. The work was largely carried out by Tom Bolderman during his graduation project, and I'm very happy that we got it out there even though it has been a few years!

I'm thrilled to share that my latest article, "𝗗𝗶𝘀𝗰𝘂𝘀𝘀𝗶𝗻𝗴 𝘁𝗵𝗲 𝗟𝗶𝗺𝗶𝘁𝗮𝘁𝗶𝗼𝗻𝘀 𝗼𝗳 𝗨𝗻𝗰𝗼𝗻𝗱𝗶𝘁𝗶𝗼𝗻𝗮𝗹 𝗦𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆 𝗜𝗻𝗱𝗶𝗰𝗮𝘁𝗼𝗿𝘀 𝗶𝗻 𝗘𝘃𝗮𝗹𝘂𝗮𝘁𝗶𝗻𝗴 𝘁𝗵𝗲 𝗧𝗵𝗲𝗿𝗺𝗼𝗮𝗰𝗼𝘂𝘀𝘁𝗶𝗰 𝗤𝘂𝗮𝗹𝗶𝘁𝘆 𝗼𝗳 𝗕𝘂𝗿𝗻𝗲𝗿𝘀 𝘄𝗶𝘁𝗵 𝗙𝗹𝗮𝗺𝗲𝘀," has just been published in the 𝘐𝘯𝘵𝘦𝘳𝘯𝘢𝘵𝘪𝘰𝘯𝘢𝘭 𝘑𝘰𝘶𝘳𝘯𝘢𝘭 𝘰𝘧 𝘚𝘱𝘳𝘢𝘺 𝘢𝘯𝘥 𝘊𝘰𝘮𝘣𝘶𝘴𝘵𝘪𝘰𝘯 𝘋𝘺𝘯𝘢𝘮𝘪𝘤𝘴. During burner development in the context of thermoacoustic instability, it’s common for acoustic domain information—where the burner will be installed—to be fully or partially unavailable. In such cases, having a criterion or indicator to determine the inherent thermoacoustic risk of the burner design is crucial. This need is at the heart of the 𝗳𝗶𝗴𝘂𝗿𝗲-𝗼𝗳-𝗺𝗲𝗿𝗶𝘁 𝗳𝗼𝗿 𝘁𝗵𝗲𝗿𝗺𝗼𝗮𝗰𝗼𝘂𝘀𝘁𝗶𝗰𝘀. In this article, we explore the concept of a figure-of-merit for thermoacoustics by applying two commonly used unconditional stability criteria from the amplifier design community. We thoroughly examine the mathematical assumptions underlying these criteria to uncover their theoretical limitations. Using a Monte Carlo simulation with specific properties, we established a reference dataset for comparison. Our investigation revealed that while these criteria can accurately predict the distribution of unstable frequencies and critical frequency bands, their use as reliable indicators for assessing thermoacoustic quality in burners is not recommended due to their mathematical limitations and overly conservative nature. So, what can serve as a suitable replacement in the context of a figure-of-merit for thermoacoustics? The answer to this question is the focus of our another manuscript, which is under review at the same journal. Stay tuned for this answer. In that manuscript, after introducing a new performance metric factor we conduct a detailed study that includes various burner design scenarios along with experimental validation of the results.

I would like to extend my heartfelt gratitude to my supervisors at Eindhoven University of Technology, Viktor Kornilov, Jeroen van Oijen, Philip De Goey at Thermo-Fluids Engineering (TFE) at TU Eindhoven, and Ines Lopez Arteaga at the Dynamics & Control (D&C) TU/e, for their invaluable guidance and support throughout. Their insights and encouragement have been instrumental in shaping this work. Feel free to comment below or reach out directly if you have any questions or would like to discuss the topic.

The ISF Committees are pleased to announce the winners of the 2024 ISF-7 Workshop prizes, recognizing outstanding contributions from PhD students and early career researchers at our seventh workshop held in Milan on 20-21 July 2024. The prize winners for the three-minute presentation competition were as follows:  Claudia-F. López Cámara, Ph.D., TU/e - EMPI – CENIDE, for a poster entitled ‘Graphene Origami : Evolution of the morphology of free-standing few-layer graphene in plasma synthesis’. Andrea Nobili, CRECK Modeling – PoliMI, for a poster entitled ‘Towards an improved description of carbonaceous particle morphology’. Let's learn a bit more about Claudia and her work in this post! Claudia’s work demonstrates, for the first time, freestanding few-layer #graphene created via microwave #plasma synthesis develops from a single layer circular-shaped graphene to a crumpled and self-folded few-layer graphene. The findings reported align with previous numerical hypotheses and open new pathways to explore in the study of the #formation and #growth of this #nanomaterial. About Claudia: Dr. Claudia-F. López-Cámara is currently an assistant professor at the Thermo-Fluids Engineering (TFE) at TU Eindhoven. Her previous postdoctoral work on experimental studies of nanomaterial synthesis at the EMPI-Reactive flows (University of Duisburg-Essen, CENIDE - Center for Nanointegration Duisburg-Essen) inspired her to pursue her career pathway in this field. Her current investigations focus on nanomaterial synthesis for energy and sensor applications. Join us in celebrating Claudia’s achievements and the promising future of nanomaterial research! #ISF7 #nanotechnology #research #innovation

🌟 Celebrating Success of the BOOST Project! 🌟 I am thrilled to share the journey of our MSc students in the Sustainable Energy Technology (SET) and Mechanical Engineering at TU/e (ME) programs, made possible through the BOOST project. Last year, we launched a new course within Thermo-Fluids Engineering (TFE) at TU Eindhoven that challenged students to innovate, collaborate, and produce cutting-edge research. Over the last quartile, six dedicated teams have poured their hearts and minds into their 8-weeks research projects. On June 20th, we had our final presentations and a round table discussion, showcasing projects on #DAC direct air capture, #hydrogen and hydrogen carrier storage, gas #purification in the petrochemical industry, and #thermochemical #energy #storage. The depth and creativity of these projects were truly inspiring. We concluded our session with open votes for the Best Project #award, selected by the students themselves. The competition was incredibly close, requiring a second round to break the tie. The two finalists were: - Separation of Butane and Isobutane in Pure Silica Zeolites - Zeolite Adsorption Potential for Thermal Energy Storage from Nuclear Energy I couldn't be happier with the dynamic of the course, the involvement and interaction of the students, and the invaluable support from my fellow teachers. Looking forward to the next edition with more exciting projects! Stay tuned for upcoming posts featuring the posters of the top two projects selected this year. 🎓🚀 #BOOSTproject #MScCourse #MechanicalEngineering #SustainableEnergy #Research #Innovation #Teamwork #StudentSuccess #TUe A big thanks to everyone involved!

📢 Publication Announcement! 📢 Are you interested in 🔥 iron combustion 🔥 ? Please check out our latest published paper titled "Iron Particles Ignition in Different Hot Coflow Temperatures" in the Proceedings of the Combustion Institute ‘40. You can read it here: https://lnkd.in/dREPkt3A. Additionally, I will be presenting this work at the 40th International Symposium on Combustion - Emphasizing Energy Transition in Milan, Italy, on July 25th, 2024 within the PPP session. 👨🔬 Our study explores the ignition of iron particles in hot environments, a crucial step for utilizing metal fuels in clean energy production. We designed an innovative single-particle burner that disperses and ignites iron particles with a heated oxidizer coflow. The burner maintains a stable and homogeneous hot coflow up to 900℃ for iron particles ignition. Ignition experiments showed that iron particles with a narrow size range do not ignite at a specific autoignition temperature; instead, their ignition behavior followed an increasing profile, starting from 5.67% at 700℃ to 99.33% at 900℃. I am sincerely grateful to my supervisors, Philip De Goey, Giulia Finotello, and Yuriy Shoshin , for their insightful guidance and support throughout this research. I'm looking forward to more in-depth discussions and interactions about our findings at the symposium in Milan! #CombustionResearch #MetalFuels #IronParticles #CombustionInstitute #ResearchInnovation #SustainableEnergy
