Analysis of Sooting Turbulent Flames with Dynamic Mode Decomposition

Abstract

This thesis is an investigation of the application of the control theory algorithm known as Dynamic Mode Decomposition (DMD) to computational combustion models. The combustion model investigated here is a Large Eddy Simulation (LES) of a piloted turbulent jet flame. This is an attempt to utilize DMD by developing a program that applies DMD to such a reacting flow model, and tries to reduce the computational demand of the basic algorithm. This work investigates problems and obstacles that arise when developing a Dynamic Mode Decomposition program to work with such a combustion mode, as well as the results of analyzing different flame parameters with DMD.
