On the understanding of spray combustion

The proposed research program aims at advancing our physical understanding of spray combustion phenomenon employed in several engineering power systems, which include air-breathing propulsion systems, diesel engines and liquid-fuelled rocket engines, among others. Two fundamental research projects related to different aspects of spray combustion are proposed, which are: (A) Experimental study of the vaporization and combustion of fuel (liquid) droplet in turbulent flow environments under realistic ambient pressure and temperature conditions, and (B) Experimental study of the break-up of a liquid jet interacting with a cross airflow. Both projects are related in that liquid break-up is the mechanism governing the formation of spray (droplets), whereas the droplet evaporation and combustion happen after the break-up of liquid jet and the formation of droplets.
