Welcome to the website for the Computational Turbulent Reacting Flow Laboratory (CTRFL) in the Department of Mechanical and Aerospace Engineering at Princeton University. Our research encompasses the development and utilization of high-fidelity computational tools to gain a fundamental understanding of and develop first-principles based models for multi-physics turbulent reacting flows, broadly defined, relevant to energy and propulsion. Much of our research focuses on turbulent combustion with engineering applications of interest including jet engines, reciprocating engines, rockets, stationary gas turbines, and furnaces/boilers. In addition, our research is rapidly expanding to multi-physics turbulent flows in other energy conversion processes relevant to wind power, concentrating solar power, nuclear fission, and nuclear fusion.
