Towards concurrent identification of flame dynamics and combustion noise of enclosed flames
نویسندگان
چکیده
The purpose of this work is to highlight the importance of taking into account the two-way interaction between flame and acoustics in the prediction of combustion noise generated by enclosed turbulent flames. It is argued that in general the power spectral density (PSD) of noise inside a combustion chamber can be determined accurately only if the influence of acoustics on the flame is considered in an adequate manner. Consequently, this work presents two techniques based on system identification (SI) to retrieve from global values of heat release rate, the sources of combustion noise as well as acoustic signals produced by acoustic excitation.

Flame stabilization by swirl is a common feature of many combustors. While most of the swirl combustors are enclosed, there have been relatively few studies of open swirl-stabilized flames. In the current study, an open swirl-stabilized turbulent premixed flame is studied numerically. The purpose of this work is to obtain a better understanding of the flame properties by simulating the flow fie...

متن کاملA New Type of Steady and Stable, Laminar, Premixed Flame in Ultra-Lean, Hydrogen-Air Combustion
Ultra-lean, hydrogen-air mixtures are found to support another kind of laminar flame that is steady and stable beside flat flames and flame balls. Direct numerical simulations are performed of flames that develop into steadily and stably propagating cells. These cells were the original meaning of the word “flamelet” when they were observed in lean flammability studies conducted early in the dev...
