Thermodynamics and fluid mechanics

IMMC

The Thermodynamics and fluid mechanics division (TFL) has been conducting research in the fileds of energy and fluid mechanics.

These two main research areas are shared between

  • Profs. Grégoire Winckelmans and Philippe Chatelain are active in advanced numerical simulations for aerodynamics, turbulent and vortical flows,
  • Profs. Francesco Contino, Hervé Jeanmart and Yann Bartosiewicz carry out research in the field of energy, while Prof. Miltiadis Papalexandris bridges the gap between these two main axes by conducting theoretical and numerical research on reactive flows in porous and granular media.

Two senior scientists support the research transversally by leading either funded projects, external contracts or engineering service

  • Dr. Véronique Dias
  • Dr. Matthieu Duponcheel

This team also supervises 48 researchers/doctoral students.

This theoretical work is also supported by experimental activities in the laboratory to validate numerical models or for dedicated experimental projects. The experimental component is possible thanks to a strong technical team (CREDEM) that is able to carry out a test bench from its design to its realisation, commissioning and testing. This involves different and complementary skills such as

  • technical drawing,
  • machining/assembly
  • electrical/electronic/data acquisition systems.

Transversally, the TFL division works under contract for several private companies and provides engineering services in different fields such as numerical simulations in fluid mechanics and heat transfer, data acquisition, calibration of measurement devices, and complete realization of prototypes from the design to the commissioning.

Besides a strongly experienced technical team, the TFL division owns state of the art simulation tools, experimental facilities and measurement devices including:

  •     High performance computing
  •     CFD codes: ANSYS CFD, OpenFoam, plus home made
  •     High speed camera
  •     Schlieren apparatus
  •     High speed stereo PIV system
  •     Laser Doppler velocimetry (LDV)
  •     Low speed wind-tunnel (open)
  •     Towing tank (13m long)
  •     Fluid characterization lab
  •     Coriolis flow meters, temperature/pressure measurements
  •     Mass spectrometer
  •     Industrial compressor (delivering 1200 Nm3/h at 40bar)
  •     200kWth gasifier
  •     Drop tube furnace
  •     Several engines
  •     Cogeneration units
  •     Ejector air conditioning
  •     Combustion chambers
  •     Large scale supersonic ejector
  •     These features provide good conditions for a well-balanced approach integrating both numerical simulations and experimental verification to achieve research and engineering projects.
