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.
