About this position

CNRS UMR 6614 CORIA in Saint Etienne du Rouvray, France is offering a PhD position on the response of spray flames from multi-component liquid fuels to standing acoustic forcing. The project focuses on how the composition of multi-component fuels with different physicochemical properties affects combustion processes and combustion instabilities, with particular relevance to sustainable aviation fuels (SAFs) as drop-in alternatives for aircraft engines.

The research aims to better understand the impact of different evaporation rates among blend components. Experiments will be carried out with air-flow temperatures above the vaporization temperature of one component. In parallel, Flame Describing Functions (FDFs), which are used in low-order thermoacoustic models, will be investigated as a function of fuel composition and operating conditions such as atomizer design, swirlers, and flame spacing. The goal is to assess the robustness of these models when dealing with the variability of multicomponent fuels.

This PhD is rooted in mechanical engineering and combustion research, and it is well suited to candidates interested in fluid mechanics, multiphase flows, acoustics, modeling, and imaging methods. The advertisement specifically asks for a Master degree or equivalent, along with experience aligned to theoretical modeling, multiphase flows, or image processing, plus a strong background in fluid mechanics and basic acoustics knowledge. Good English is required.

The position is based at CORIA, part of CNRS, in France. The contract is full-time and temporary, with one position available. The advertised starting date is 1 October 2026, and the application deadline is 18 September 2026 at 18:00 (Europe/Paris). Interested candidates should apply through the CORIA job page and consult the full advert for further details.
