Turbulent Reacting Flow Research

Chemical Engineering Department

Brigham Young University



The CRFlow group studies fundamental aspects of turbulent reacting flows through high performance computing, with an emphasis on combustion in nonpremixed flames. The group is led by David O. Lignell, who is an Associate Professor in the Chemical Engineering Department and teaches courses in computational tools, numerical methods, combustion, fluid mechanics, and career skills.

Our research focus is on flames and fires including soot formation, flame extinction and reigntion phenomena, and multiphase flows including coal and biomass combustion, and Lagrangian particle transport. Combustion is central to society and approximately 85% of the world's energy derives from the burning of fossile fuels. Indeed, we heat our homes, drive our cars, and light our lives by the energy of the flame. We are working to improve modeling and simulation capabilities of turbulent reacting flows to develop a better fundamental understanding of the key physics, to generate high fidelity data for model validation, and to develop and improve models for combustion engineering, design, and hazard analysis. We use primarily three complementary simulation approaches: DNS, LES, and ODT, and are developing a novel simulation technique called autonomous microstructure evolution (AME).
