ABSTRACT:

Reliable prediction of the performance of modern aerospace combustion
devices poses numerous challenges, in terms of both modelling and numerical
implementation. This talk will provide an overview of some of these
challenges. Monte Carlo methods for simulation of turbulent reactive flow
are an effective solution to the chemical composition turbulent closure
problem, but require an increase of the computational cost to keep the
sampling error at a reasonable level. Laser-induced breakdown in high speed
combustors has exciting potential as a control actuator, but requires
correct modelling at both the high-temperature plasma regime and the energy
containing neutral combustion regime. Accurate simulation of reactive
processes using real fuels necessitates algorithms which can efficiently
handle chemical mechanisms with hundreds of species and thousands of
reactions. The simulation of combustion instability and the design of
control strategies to prevent it combines all of these challenges.
Solutions to overcome them are being pursued by the Popov research group,
and will be described in this talk.


Pavel Popov is an Assistant Professor in the Department of Aerospace
Engineering, specializing in computational combustion. His doctoral work
focused on stochastic methods for the simulation of turbulent reactive
flows. Prior to coming to SDSU in Fall 2019, he pursued post-doctoral
projects in combustion-acoustic instability in rocket engines and modelling
of plasma-combustion coupling. His research interests are in numerical
simulation of reactive flows, high-performance computing, stochastic
simulation and machine learning applications in computational combustion.
