Experimental Devices for Burning Particles and Vaporizing Drops at High Pressure
Contact : Christian CHAUVEAU
High pressure chamber
This chamber is equipped with an electrostatic levitation unit allowing the study of particle combustion without contact. The ignition is ensured by a CO2 laser.
• Maximum pressure : 12 MPa
Combustion chamber and high pressure levitation
Types of particles
Different types of particles can be studied in this device :
• Al, AL-Ni, Mg, Fe
• Coal, lignite, petroleum coke
The ignition delay and combustion time of these particles can be determined as a function of the parameters: pressure and composition of the ambient gas.

Microgravity droplet spray device (MUCC) on board the A300, 0g
The vaporization of the drops is studied in a chamber that can be embarked on board the A300 0g aircraft, which can create conditions of reduced gravity.
Max temperature : 1200 K
