“…Nevertheless, multiple studies show that flames nearby a solid surface respond differently to acoustic perturbation, depending on the surface temperature [21,22,23,24,25,26,27]. We therefore seek how the flame-root region, which is close to the solid boundary, may alter the flame response.…”

“…For example, on the deepest level one can study the complicated interaction between local (turbulent) flow dynamics, chemical kinetics, and heat release [7]. On the element level one may be interested in the acoustical response of an unflanged open end [8], or the acoustical response of a flame [2].…”

“…It is well-known that heat losses introduced by ame-holders or by walls close to the stabilization zone of ames induce strong changes on the ame topology even in the absence of any instability [37,108] . For porous burners, the whole stabilization process and the ame response to unstable perturbations is controlled by heat losses to the porous plate [109][110][111] .…”

“…Its objective is to describe modern simulation methods combined with new experiments and theoretical developments for such instabilities. Readers are referred to other reviews for complete descriptions of instability mechanisms [20,[35][36][37] . Of course, the presentation builds on fundamental results obtained for CIs in laboratories over the last hundred years but its main goal is to discuss what must be added to these elements when real engines are considered.…”

To cite this version: AbstractThis paper presents recent progress in the eld of thermoacoustic combustion instabilities in propulsion engines such as rockets or gas turbines. Combustion instabilities have been studied for more than a century in simple laminar con gurations as well as in laboratory-scale turbulent ames. These instabilities are also encountered in real engines but new mechanisms appear in these systems because of obvious differences with academic burners: larger Reynolds numbers, higher pressures and power densities, multiple inlet systems, complex fuels. Other differences are more subtle: real engines often feature speci c unstable modes such as azimuthal instabilities in gas turbines or transverse modes in rocket chambers. Hydrodynamic instability modes can also differ as well as the combustion regimes, which can require very different simulation models. The integration of chambers in real engines implies that compressor and turbine impedances control instabilities directly so that the determination of the impedances of turbomachinery elements becomes a key issue. Gathering experimental data on combustion instabilities is dif cult in real engines and large Eddy simulation (LES) has become a major tool in this eld. Recent examples, however, show that LES is not suf cient and that theory, even in these complex systems, plays a major role to understand both experimental and LES results and to identify mitigation techniques.
