The Effects of Turbulence on Jet Stability and the Flame Transfer Function in a Lean-burn Combustor

, 2020
Large eddy simulations show that the penetration of the central jet in a multi-passage lean burn and liquid fueled combustor is dependent on the turbulence levels in the three air-flow passages of the injector.

Flame transfer function shaping for robust thermoacoustic systems: Application to a kinematic flame model

International Journal of Spray and Combustion Dynamics
This work presents a data-driven optimization technique for the optimization of the flame response within a low-order acoustic network model. The methodology exploits the Nyquist criterion to compute a measure of thermoacoustic robustness at targeted ...

Experimental Investigation of Thermoacoustics and High-Frequency Combustion Dynamics with Band Stop Characteristics in a Pressurized Combustor

Energies
In combustor systems, thermoacoustic instabilities may occur and must be avoided for reliable operation. An acoustic network model can be used to predict the eigenfrequencies of the instabilities and the growth rate by incorporating the combustion ...
