Large Eddy Simulation of the Pulsating, Non-Reacting Flow in Combustion Chambers

Abstract

In the present work a numerical investigation of the pulsating, non-reacting flow in a combustion chamber, and a coupled system of burner plenum and combustion chamber is presented. The results are compared with an analytical model and experimental data. The numerical simulations provide the damping ratio, an important input, for the analytical model, which was developed to predict the stability limits of technical combustion systems.
