Paper Abstract

The improvement of the combustion performance in combustor engines in terms of the reduction of the pollutant emissions is an important objective in Automotive and Aerospace Research and Development. Many phenomena occur during the spray injection in the combustor engine: droplet turbulent dispersion, droplet wall interaction, droplets interaction, droplet evaporation, primary and secondary breakup, auto- ignition, combustion, etc. To improve and to validate the heat exchange models between the droplet and a heated wall, an experimental set-up is developed at the ONERA Toulouse Centre on fundamental studies involving single droplets. An Infrared detector measures the temperature evolution of the surface droplet which impinges on a heated wall.
