My research lies at the intersection of combustion, fluid mechanics, acoustics, and controls. Much of this work is directed toward development of clean combustion energy systems for power generation, aircraft propulsion, or refining/process industries. Unsteady combustor phenomenon have emerged as one of the leading barriers to robust, reliable operation of clean energy systems and high performance combustion systems. These include blowoff - which refers to the flame physically "blowing out" of the combustor, flashback, referring to flame propagation upstream into components not designed for high temperatures, or combustion instabilities, which refers to damaging acoustic oscillations.
The work involves coordinated experiments, computations, and theoretical analyses. Experiments generally use state of the art laser diagnostics to characterize the unsteady velocity field and flame dynamics. Computations are used to simulate flame and flow dynamics and theoretical analyses are used to provide insight for limiting cases.
