Spray combustion has tremendous engineering applications in different fields varying from energy conversion devices to rocket propulsion system. Developing accurate models for turbulent spray combustion is vital for improving the design of combustors involving spray combustion. Flamelet models are attractive for modeling spray combustion due to their relatively low computational cost. These models heavily rely on a rigorous parameterization of spay combustion in laminar flamelet. In this work, we aim to study the characteristics of spray combustion in laminar flamelet and to develop parameterization of the flame characteristics, by performing detailed calculations of laminar spray jet flames under a counter-flow configuration. A conserved scalar called mixing variable is introduced to characterize the mixing field. The flamelet structures under different rates of strain are investigated to help understand the characteristics of spray combustion. The interactions between flames and spray dynamics are also examined. The results and the gained understanding will enable us to develop flamelet models for turbulent spray flames.

What is the Research Symposium Series?

The Research Symposium Series is a department-sponsored forum for graduate students and advanced-level undergraduates to present their research to a general audience.

The Research Symposium Series is designed to: 

• Facilitate the exchange of ideas and knowledge among faculty and graduate students.
• Provide opportunities for students to develop their technical presentation skills.
• Promote the research activities of the department to undergraduates and other interested individuals.

2017 Prizes

• $500, $300, $200 for best three presentations
• $150 for best undergraduate presentation
• $150 for best abstract
