At the 41st International Symposium on Combustion in Kyoto, Gianmarco Lemmi presented his work “Bridging the Thickened Flame and Fine-Scales frameworks for multi-regime combustion modelling”. In this work, developed with S. Castellani, R. Meloni, and A. Andreini within the TRANSITION Project, it was proposed a unified TF–FS framework for LES of flames in which premixed and non-premixed combustion modes coexist. The model dynamically combines Thickened Flame and Fine-Scales approaches, showing promising results across several test cases and industrial applications. The presentation also sparked valuable discussions and new perspectives for future research.

Gianmarco Lemmi presented his work “A Unified Thickened Flame–Fine-Scales Framework for Multi-Regime Combustion Modelling: Application to an Industrial Lean-Premixed Burner” at ASME Turbo Expo, 15-19 June 2026, Milan, developed in collaboration between Università degli Studi di Firenze and Baker Hughes under the TRANSITION Project.

In this work, it is proposed a unified Thickened Flame–Fine Scales framework capable of handling different combustion regimes within a single primitive variables-based modelling approach and demonstrate its application to an industrial lean-premixed burner.

The questions and discussions following the presentation were definitely the highlight of the conference.

Congratulations to Sofia Galeotti, recipient of the 2026 Antonio D’Alessio Award, a prestigious recognition presented by the Italian Section of The Combustion Institute – ASICI for outstanding doctoral research in combustion science and energy transition, during the joint meeting of the Italian and Spanish Sections held in Sorrento.. These accomplishment demonstrates the impact of TRANSITION not only in advancing cutting-edge technologies for low-carbon power generation, but also in supporting the development of the next generation of researchers and innovators.

On February 5 and 6, 2026, UNIFI (Antonio Andreini and Sofia Galeotti) visited the new combustion test facilities developed at Orta Doğu Teknik Üniversitesi / Middle East Technical University (Ankara, TR), where further experimental investigations will be conducted as part of the TRANSITION project.
The METU team will test 𝐄𝐆𝐑 optimized burners for Baker Hughes gas turbines developed as part of the project, focusing on the most aggressive solutions that exploit localized injections aimed at improving flame stability with high EGR rates

Next Internal Technical Review meeting will take place in Trondheim (NO) next April 14, in a full day format, hosted by SINTEF Energy Research

The first 𝐏𝐮𝐛𝐥𝐢𝐜 𝐖𝐨𝐫𝐤𝐬𝐡𝐨𝐩 event of the project 𝗧𝗥𝗔𝗡𝗦𝗜𝗧𝗜𝗢𝗡 will be held next May 21st in Florence, kindly hosted at the Florence Learning Center of Baker Hughes
The event represents the planned mid-term dissemination action of the project, and will showcase the TRANSITION partners’ recent achievements in improving knowledge on the use of 𝗘𝗚𝗥 (Exhaust Gas Recirculation) in heavy-duty gas turbines to enable more efficient adoption of carbon capture technologies (𝗖𝗖𝗨𝗦).
Project partners will present outcomes achieved in the first two years of the project. The workshop will also see the contributions by two external experts as Invited Speakers: Prof. Epaminondas Mastorakos and Prof. Ward De Paepe.

Elettra Vantaggiato, from SINTEF Energy, presented part of a work on Project ACCSESS, Cleanoff Hub and TRANSITION Project during the 17th International Conference on Greenhouse Gas Control Technologies (GHGT-17), 20th -24th October 2024, Calgary Canada. The poster presentation was a synergistic effort with the project CleanOFF Hub
