The main research interests of Thierry Schuller are focused on a fundamental understanding of flame acoustic interactions and oxy-combustion, and the transfer of this knowledge to develop engineering tools for practical applications. The approach taken to improve the understanding of these phenomena and their modeling is based on a hierarchy of experimental benchmark configurations of rising complexity. This sequence of investigations span from atmospheric laminar flames and swirling flames fed by gaseous and liquid combustibles, to high pressure and multiple injector combustors like in gas turbine combustors or industrial boilers. These test rigs are used to determine the main flow quantities of interest, analyze the physics of the flame behavior and its interaction with acoustics and heat transfer. This is carried out with close collaboration with researchers from numerical combustion who take advantage of these comprehensive data for the purpose of validation. Physics based models of the phenomena observed in these combustors are used to interpret and model their behavior in practical systems.
There are strong international ties with a large number of groups, experimental and numerical. The work has been awarded by several prizes and invitations to plenary lectures. Thierry Schuller authored and coauthored more than 60 archival journal publications.
