Numerical Simulation of Turbulent Combustion

10:30 AM-12:30 PM
New Hampshire 3

Turbulent combustion plays a critical role in both transportation and energy production. The interplay between chemical reactions and turbulent flow determines the efficiency of combustion devices as well as their pollutant emissions. One tool for studying turbulent combustion is direct numerical simulation in which the fluid-dynamic scales are fully resolved. These types of simulations combine turbulent fluid mechanics with complex reaction and transport for multicomponent mixtures, resulting in demanding computational requirements that necessitate high-performance parallel architectures. In this minisymposium, the speakers will discuss methodologies and current capabilities for modeling turbulent reacting flow, focusing on simulations with realistic kinetics mechanisms.
