Efficient nonlinear flame response modeling for propulsion thermoacoustic analysis using limited numerical data
Jiawei Wu, Teng Wang, Jiaqi Nan +3
Characterizing nonlinear flame response is critical for predicting thermoacoustic instabilities in propulsion combustors, yet obtaining a comprehensive response map through high-fi…
On the flame transfer function models for laminar premixed conical and V- flames considering the stretch effect
Yu Tian, Lijun Yang, Aimee S. Morgans +1
This paper investigates a predictive model that considers the impact of stretch on the dynamic response of laminar premixed conical and V- flames; the flame stretch consists of two…
Nonlinear responses of the premixed V-flame subjected to dual-frequency disturbances
Xiaozhen Jiang, Xiaokang Liu, Aimee S. Morgans +5
The two-way interaction between the unsteady flame heat release rate (HRR) and acoustic waves can lead to combustion instability within combustors. Previous studies have typically…
Analytical solutions for the acoustic field in thin annular combustion chambers with linear gradients of cross-sectional area and mean temperature
Dongbin Wang, Jiaqi Nan, Lijun Yang +2
Predictions of thermoacoustic instabilities in annular combustors are essential but difficult. Axial variations of flow and thermal parameters increase the cost of numerical simula…
Theoretical analysis of sound propagation and entropy generation across a distributed steady heat source
Jiaqi Nan, Jingxuan Li, Aimee S. Morgans +2
Acoustic and entropy waves interacting in a duct with a steady heat source and mean flow are analysed using an asymptotic expansion (AE) for low frequencies. The analytical AE solu…
