A Brief Review of Acoustic Excitation Toward Jet Flame Characteristics

Abstract

Acoustic interaction toward jet flame in a combustion system is essential to understand the characteristic of combustion instability. Combustion device such as turbine, ramjets, industrial processor, jet rocket and other mostly occurrence for self-excited due to mechanical part and coupling. The combustion driven oscillation can affect the combustion system life and performance. This paper is mainly focused on the characteristic of the flame, which having interacted with the acoustic excitation. This paper is organized into three parts. First part is the introduction, follows by the literature review, which mainly focused on the physical characteristic of the flame, the structure, the length, the shape, and the color of the flame. Then the last part consists of the subject goes toward the application of acoustic perturbation – utilizing acoustic excitation toward good intention, the formation of soot and nitride oxide reduction.
