This PhD project focuses on Food Oral Processing and the development of bioinspired robotic and sensor-based tools to better understand how food structure and acidity influence salivation, mastication, bolus formation, texture perception, and swallowing. The work is rooted in ongoing efforts to reproduce oral processing mechanisms realistically and holistically in vitro. The doctoral research begins with a detailed review of the scientific literature on salivation mechanisms, then moves to the d...

About this position

This fully funded PhD position at IFP Energies nouvelles (IFPEN) in France focuses on the detailed numerical simulation of porous media combustion using ammonia and hydrogen as fuels. The project addresses the urgent need for low-emission, carbon-free burners in response to climate change regulations. Ammonia and hydrogen are promising carbon-free fuels, but each presents unique challenges in combustion, storage, and emissions. The research will explore the use of porous burner technology, which can stabilize flames at low fuel/air equivalence ratios (FAER) and potentially reduce NOx emissions through heat recirculation within the porous matrix.

The PhD will employ advanced computational fluid dynamics (CFD) techniques, specifically direct numerical simulations (DNS) using the CONVERGE code with adaptive mesh refinement. The work will involve modelling complex multi-physics phenomena, including heat conduction, radiative transfer, flame stabilization, and surface chemistry. The project will use reduced mechanisms for NH3/H2 combustion chemistry and incorporate conjugate and radiative heat transfer. The research is conducted in collaboration with CEA and will focus on a reference experimental setup, systematically investigating parameters such as FAER, inlet mass flow, and porous topology. The role of surface chemistry in NOx emissions will be a key area of study, with the aim of publishing results in peer-reviewed journals.

Supervision is provided by Dr Olivier COLIN and Dr Karine TRUFFIN at IFPEN, with the doctoral school affiliation at Université Paris-Saclay (ED 579 SMEMAG). The position is funded by the PEPR SPLEEN AMHYABLE project, offering a competitive salary, benefits, and access to state-of-the-art laboratory and computing facilities. PhD students benefit from a stimulating research environment, dedicated seminars, and training sessions.

Eligibility: Applicants must have a Master’s degree (or equivalent) in Mechanical Engineering, Computer Science, Fluid Mechanics, or Energetics. Required skills include programming (Python, C++), numerical analysis, and an excellent command of English. Experience with CFD and combustion modelling is highly desirable.

Application deadline: 30 September 2026. The position starts on 2 November 2026. For more information, visit the IFPEN website or the project page.

How to apply: Send your application (cover letter, CV, and transcripts) to Dr Karine Truffin at [email protected]. Early applications are encouraged.
