Combustion and Propulsion Laboratory

Combustion and propulsion research is both fundamental and practical, incorporating fluid dynamics and thermodynamic as its basis and contributing majorly to the research and development of advanced energy systems and aerospace/defense systems in its application. The Combustion and Propulsion Laboratory uses advanced computational fluid dynamics tools for reacting flows to investigate intriguing transient phenomena of reactive systems resolving involved multiscale fluid dynamics and thermochemical process, thereby enabling high fidelity modeling and simulation of practical combustion and propulsion systems. Though our research, environmental and safety concerns are addressed by seeking the optimal operating conditions for minimizing environmental impact, and for securing safety regime. This area of research is by nature multidisciplinary, welcoming collaboration across applied mathematics, physics, chemistry, computer science, and mechanical engineering.
