Prediction of stability behaviors of longitudinal and circumferential eigenmodes in a choked thermoacoustic combustor

Study of KJ-66 micro gas turbine compressor: Steady and unsteady Reynolds-averaged Navier–Stokes approach

“…[6][7][8][9][10][11] MGT differs itself from conventional gas turbine due to its low operating Reynolds number and hence a relatively higher skin friction and heat transfer rate. 12,13 Existing research mainly focuses on the design of the engine, 14,15 combustor development, [16][17][18] combustion and emission, 9 combustion instability, 19,20 heat transfer, 21 control strategy, 22 etc. Specific study about the MGT compressor is still limited, although preliminary studies do have addressed this issue in some aspects.…”

Transient energy growth analysis of a thermoacoustic system with distributed mean heat input

“…10 and 11. It means that the forms of distribution of the mean heat input have little influence on the transient growth of total energy in the thermoacoustic system [47][48][49][50][51].…”

Analytical solutions for the acoustic field in thin annular combustion chambers with linear gradients of cross-sectional area and mean temperature

“…Thermoacoustic instability is of concern in applications such as gas turbines and aero-engines, leading to research into instability problems in combustion chambers [1,2] and the acoustic field in combustors [3,4,5,6]. Experiments and detailed numerical simulations are typically very expensive [7], making them less suitable for industrial design and prediction.…”
