| 1. | The droplet and the engine - Zoom in the Lab |
| | Temperature distribution in a droplet : measurement by LIF (Laser Induced Fluorescence).Given the importance of the evaporation phase for combustion performance, it is clear that we have to analyze the droplet mist from all angles (size and speed of droplets, average temperature, temperature distribution within the drop, flow rate, etc.) in order to understand how the droplets behave when passing from the liquid to the gaseous state.... |

| 4. | Optical diagnostics of nanotubes synthesis - ONERA / DMPH-EN |
| | The measured temperature gradient has served to validate the fluid dynamics simulations of the laser-vaporization reactor by means of the MSD code from ONERA (DEFA).LIF spectroscopy has been applied to probe the atomic and molecular species formed in the vaporization plume.. In the case of carbon / catalysts plume, Ni, Co, Fe, Y atoms and C2, C3 molecules have been diagnosed.. |

| 5. | Nanotubes synthesis reactor by continuous laser vaporization - ONERA / DMSC-EN |
| | Others optical diagnostics are developed : the Laser Induced Fluorescence (LIF) for the analyse of the species present in the gas phase at the top of the target, and the Laser Induced Incandescence (LII) for the measurement of the density and the size of the particles in the gas flow.... |

| 9. | Plasmas for Combustion Control / Abstracts |
| | By the mid eighties, Laser-Induced Fluorescence (LIF) matured to the point of allowing semi-quantitative tomoscopic imaging of radicals and of temperature in flames, procuring remarkable insight into the flowfield dynamics and the chemistry of jet engines or piston engines.... The lecture will cover recent accomplishments using CARS and LIF at the LAERTE laboratory of ONERA.... |
