DC2: Temperature, velocity and water measurements in H2/air mixture using 1064 nm Laser-Induced Grating Spectroscopy (LIGS) under reactive and non-reactive conditions
My DC project focuses on simultaneously measuring temperature, velocity and composition in H2/air free jets under both reactive and non-reactive conditions. I will use Laser-Induced Grating Spectroscopy (LIGS) to acquire experimental data, which will then be used for validating numerical simulations. The broader goal is to develop a detailed understanding of H2/air mixing behaviour across a range of conditions and to evaluate the ignitability of the mixture at different pressure levels.
Measuring temperature and the concentration of reactants and products in chemically reactive flows using spatially and temporally resolved optical diagnostic techniques is valuable for both validating computational models and supporting safety assessments. Through this fundamental research project, I aim to generate key insights that support the use of hydrogen and ammonia as alternative fuels in combustion engines, thereby contributing to the decarbonisation of the transportation sector.

About me
I began my engineering journey with a Bachelor’s degree in Mechanical Engineering, with a clear intention to further specialise in Aerospace through a Master’s degree. I pursued this path and graduated from ISAE-ENSMA in 2025. During my Master’s, I focused on combustion and fluid mechanics, gaining hands-on experience in both numerical and experimental methods.
In my final semester, I joined L’Institut Jean Le Rond d’Alembert at Sorbonne Université as a research intern. My work involved stability analysis of helical vortices using an in-house numerical tool, where I generated large sets of baseflows and performed stability analyses to investigate the behaviour of unstable modes under different parametric conditions. This experience provided my first in-depth exposure to research practice, including scientific documentation, identifying gaps in the literature, and collaborating with a research team
I am now working and developing as an MSCA researcher, focusing on understanding the complexities of hydrogen as a sustainable fuel for a cleaner future. I am particularly motivated to collaborate in an international environment and to continuously refine and expand my knowledge.
I am inspired by Marie Curie’s words: “I was taught that the way of progress was neither swift nor easy.” This resonate strongly with my approach to research, and I look forward to contributing collaboratively within DT-HATS to advance meaningful progress towards a more sustainable future.
