Modeling of Self-Oscillation in Combustion Chambers

Аннотация

In this paper, we present a turbulent combustion model for calculating self-oscillations in combustion chambers. The model is based on the large eddy simulation (LES) method in conjunction with the global methane combustion mechanism. We numerically simulated self-oscillations in a laboratory combustion chamber. The fist longitudinal mode of oscillations is shown to be correctly predicted by modeling.
