To conclude the first day of the 2nd Congress of the PPGEM EP USP, check out Felipe's work. PhD student: Felipe Silva Maffei Title: A framework for large-scale fluid topology optimization considering compressible and turbulent flows Abstract: The human impact on nature is meanly observable by the increase in global average temperature leading to more frequent extreme events like floods, droughts, and bushfires. The cause is predominantly associated with the imbalance of the greenhouse effect due to human activity, which, in normal conditions, is essential for Earth’s habitability. A complete scenario of a perturbed global system is unavailable with potentially hazardous results. Consequently, efforts across the public, industrial, and political sectors to reverse this scenario are spreading across the globe. Especially, the mitigation of gas emissions such as methane and CO2, particularly due to its potency, short atmospheric lifespan, and the amount realized, underscores global efforts. This study proposes the development of a topology optimization tool for compressible and turbulent fluid systems, the principal energy sector characteristics (pivotal for emissions and human life). Topology optimization is the most generic kind of optimization methodology, being necessary only for the mathematical model of a given physics and an objective function to achieve a non-intuitive design.

𝐒𝐡𝐢𝐩 𝐝𝐞𝐬𝐢𝐠𝐧 𝐭𝐨𝐰𝐚𝐫𝐝𝐬 𝐝𝐞𝐜𝐚𝐫𝐛𝐨𝐧𝐢𝐳𝐚𝐭𝐢𝐨𝐧? 𝐎𝐯𝐞𝐫𝐥𝐨𝐨𝐤𝐞𝐝 𝐝𝐞𝐬𝐢𝐠𝐧 𝐜𝐡𝐚𝐥𝐥𝐞𝐧𝐠𝐞𝐬 𝐢𝐧 𝐥𝐢𝐟𝐞𝐜𝐲𝐜𝐥𝐞 𝐚𝐬𝐬𝐞𝐬𝐬𝐦𝐞𝐧𝐭? This June I participated in the #IMDC conference in Amsterdam. IMDC proved a great platform to get updated on the ship design developments. I presented part of my research titled "Integration of the methanol power propulsion and energy systems’ (EC) temporal uncertainties in a Markov decision process framework", co-authored by my supervisors: Austin Kana and Jeroen Pruyn. This study proposes a design method to bridge two normally disassociated fields by combining the use of (1) Markov decision processes to assess uncertain future methanol EC developments during the vessel lifecycle and (2) a generative probabilistic layout algorithm to quantify the risks associated with the EC systems layout integration. The coupling of MDPs with the probabilistic layout tool proved a method that can account for technical, environmental, and financial uncertainties relative to the various alternative power and energy systems configurations. Using this framework as a baseline, we aim to produce insights for design pathways to be selected towards decarbonization under uncertain conditions. 🌟 Interested to find out more about this study?

💡We're glad to share a RES Success Story aiming to bring closer hydrogen as a low-emission energy source candidate 💡 📋Numerical study of the propagation patterns of hydrogen-air flames in Hele-Shaw chambers led by Marie-Anne Dejoan from CIEMAT ♻️ The study aimed to tackle current safety concerns regarding the potential use of hydrogen as a low-emission candidate to replace carbon fuels 🔥The research team reproduced the complex flame dynamics of lean hydrogen in a very confined geometry, especially the formation of two-headed and fractal cell patterns 🖥️ Thanks to RES supercomputer #MareNostrum4 from Barcelona Supercomputing Center, they showed that temperarure - which is hardly measurable in experiments - is large enough at the highly-curved head cells to ensure combustion, allowing for stable propagation under large heat loses With all the data gathered using #HPC resources, they also inferred an interplay between the equivalent ratio and heat loss parameters for the flame cell regime to occurr

😊 My name is Kathrin Eckert and I work at the CRC 1615 on project A01 "Stimuli-responsive polymers for self-regulating reactors: From basic phenomena to reactor design" at Hamburg University of Technology. 🚀 The focus of my work in the Institute for Thermal Separation Processes is on smart lyogels, modeling them and improving their properties to build a SMART reactor. 💡 I got into the field when I was doing my Master's thesis on smart lyogels, and I liked how these materials can work completely autonomously. 🌍 Chemical reactors were not developed further since many years and I want to take the chance to change the world by creating new and SMART reactors. 🤝 If I were to describe the CRC in three words they would be: 🔷Team 🔷Fun 🔷Research. #SMARTreactors #TUHH #Technischistdasmöglich #TUHamburg #engineeringtofaceclimatechange

🌟 Exciting News! 🌟 I’m thrilled to announce that our conference paper titled "Nanofluid Flooding in Porous Medium for Enhanced Oil Recovery" has been published in the AIP Conference Series! In our research, we explored the innovative technique of nanofluid flooding to enhance oil recovery (EOR). By simulating two-phase fluid flow in a two-dimensional porous medium, we investigated the effects of various nanoparticles (SiO2, Al2O3, CuO) on EOR performance. Our findings demonstrated that incorporating nanoparticles at a 5% volume fraction significantly increased oil recovery by over 18%. This work underscores the potential of advanced methods in EOR, particularly with the integration of thermophysical property correlations and temperature effects. I’m proud to contribute to this important field and look forward to the discussions and advancements this research will inspire!
