IUSTI

What IUSTI does

IUSTI (Institut Universitaire des Sciences Thermiques et de l'Ingénierie) is a public research laboratory designated as UMR 7343, jointly operated by CNRS (Centre National de la Recherche Scientifique) and Aix Marseille Université, and located in Marseille, France. Founded in 1985 with a current headcount of 23, the laboratory is centered on engineering sciences — specifically mechanics and energetics — and addresses applied problems across industry, environment, and health sectors.

Research is organized around three axes: FETH (Feux, Energétique, Thermique et Hydrodynamique) covering fire, energy, thermal and hydrodynamic phenomena; ECOCI (Écoulements Compressibles, Ondes de Choc et Interfaces) addressing compressible flows, shock waves, and interfaces; and SOFT (Solides & Fluides Complexes) focused on complex fluids and solids. The laboratory supports its research with in-house platforms including scientific computing infrastructure, experimental support (acquisition and instrumentation, mechanical realization), and 3D additive manufacturing capabilities. It is affiliated with the Fédération PEIRESC research federation, the École Doctorale ED353 graduate school, and Polytech Marseille engineering school, and produces work published in top-tier journals including PNAS and Physical Review X.

IUSTI does not commercialize products or services and has no pricing or revenue model. Its 'business model' consists of public research funding from CNRS and Aix Marseille Université, supplemented by academic-industry collaborations. Outputs are disseminated via scientific publications, seminars, hosted international schools (e.g., IUVSTA 2023, ESIA 2022), doctoral and postdoctoral training programs, and science outreach events. Stakeholders include research institutions, academic partners, and industry partners seeking applied research in thermal sciences, combustion, and fluid dynamics.

Core offering

IUSTI is a public research laboratory that conducts fundamental and applied research in engineering sciences, with emphasis on mechanics and energetics. Its work spans three research axes — FETH (Fire, Energy, Thermal and Hydrodynamics), ECOCI (Compressible Flows, Shock Waves and Interfaces), and SOFT (Complex Fluids and Solids) — supported by scientific computing services and an experimental platform covering instrumentation, mechanical fabrication, and 3D additive manufacturing. The lab also offers doctoral training, internships, and postdoctoral positions through its partner institutions.

Product overview

IUSTI is a CNRS-Aix Marseille University mixed research unit (UMR 7343) focused on engineering sciences. The laboratory conducts research in mechanics and energetics, addressing applications in industry, environment, and health. It is structured around three research axes: (1) FETH – Feux Energie Thermique Hydrodynamique (Fire, Energy, Thermal and Hydrodynamics), (2) ECOCI – Écoulements Compressibles, Ondes de Choc et Interfaces (Compressible Flows, Shock Waves and Interfaces), and (3) SOFT – Solides & Fluides Complexes (Complex Fluids and Solids). The laboratory also provides research support platforms including scientific computing services, experimentation support (acquisition & instrumentation, mechanical realization, additive manufacturing/conception 3D), and administrative services. IUSTI does not offer commercial products or services but rather conducts fundamental and applied research with associated publications, seminars, doctoral programs, internships, and postdoctoral positions.

Direct peers

• EM2C (Énergétique Moléculaire et Macroscopique, Combustion): CNRS-CentraleSupélec lab dedicated to combustion and energetics research — directly comparable to IUSTI's FETH axis on combustion and thermal sciences.
• CORIA (Complexe de Recherche Interprofessionnel en Aérothermochimie): CNRS-INSA-Rouen joint unit on aero-thermo-chemistry, combustion, and compressible flows — strong overlap with IUSTI's ECOCI and FETH axes within the same French public research ecosystem.
• ICARE (Institut de Combustion, Aérothermique, Réactivité et Environnement): CNRS-CEA-Orléans joint unit focused on combustion, aerothermics, and reactive flows — closely aligned with IUSTI's FETH fire/combustion research axis.
• Institut Pprime: CNRS-Université de Poitiers-ISAE-ENSMA joint unit covering fluid mechanics, thermal sciences, and combustion — overlaps with all three of IUSTI's research axes.
• CETHIL (Centre d'Énergétique et de Thermique de Lyon): CNRS-INSA Lyon lab on thermal science, energetics, and heat transfer — directly comparable to IUSTI's thermal and energy research axis (FETH).
