David Lignell
Dr. Lignell is an Assistant Professor in the Chemical Engineering Department at
Brigham Young University. His research area is computational modeling and
simulation of turbulent reacting flows with an emphasis on combustion. He
recieved his B.S. and Ph.D. Degrees in Chemical Engineering from the University
of Utah in 2001, and 2008, respectively.
From 2001-2003, he worked as a
conulting Engineer for Reaction Engineering International.
Dr. Lignell's graduate research was conducted as a graduate student intern at the Combustion Research Facility (CRF) at Sandia National Labs working with Dr. Jacqueline Chen. His work centered on direct numerical simulation of turbulent nonpremixed flames including soot formation and transport, and flame extinction and reignition phenomena. An image of soot mass fraction in an ethylene jet flame is shown below. DNS provides unparalled insight into turbulent flame structure, along with high fidelity data for model validation. In 2008, Dr. Lignell worked as a post doctoral researcher at the CRF with Alan Kerstein on the one dimensional turbulence model, and a related, novel simulation technique call autonomous microstructure evolution or AME.
