Computational modeling of turbulent spray combustion

 

Spray flames are widely used in industrial furnaces, power generation system, etc. and there is a need for computational models to predict their properties. The objective of this project is to develop and validated accurate and efficient modeling approaches for turbulent spray combustion. The models should describe the main physical and chemical processes, notably phase change, turbulence, chemical reaction and radiation and their mutual interactions.  Models will be developed for dilute spray combustion and for the coupling between dense spray and dilute spray regions.

Progress

The PhD project is completed. On May 17, 2016, Likun has received the doctor degree, with designation Cum Laude.
