"ADNS Perspective on the Turbulent Premixed Flame Regime Diagram"

Tuesday August 29 @ 2 p.m.
Food Processing Technology Building Auditorium
NARA complex

Abstract:
Over the last decade or so, three-dimensional Direct Numerical Simulation (DNS) with detailed chemistry has provided unique insight into the small-scale interactions between turbulence and premixed flames.  In this talk, a DNS perspective will be presented of the turbulent premixed flame regime diagram, primarily through canonical flame-in-a-box calculations.  Interpretation of the dimensionless groups will be considered, along with consequences for the demarcations between burning regimes.  Topics of particular focus will include the influence of Karlovitz number and the transition towards distributed burning, effects due to Lewis numbers of different species, and the response observed in chemical distribution.

Bio:
Dr. Apsden joined Newcastle University in January 2017 as a Lecturer of Thermofluid Dynamics.  He obtained an MMath from the University of Oxford in 2002, followed by a PhD in Applied Mathematics from the University of Cambridge in 2006. He was awarded a Glenn T Seaborg Fellowship at the Lawrence Berkeley National Laboratory, where he was a member of the Center for Computational Sciences and Engineering for five years. Before joining Newcastle University, he was a Lecturer of Applied Mathematics at the University of Southampton, a Lecturer of Computational Fluid Dynamics at Cranfield University, and before that a Lecturer of Engineering Sciences at the University of Portsmouth. Andy's research interests include analysis and simulation of fluid mechanics, turbulence, combustion, and type Ia supernovae.
