QUENTIN DOUASBIN is an academic who published a paper in 2017 entitled Analysis of coaxial-flame response during transverse combustion instability. QUENTIN DOUASBIN published this work as part of a team: URBANO, Annafederica. Here is a description of this work: This paper presents the investigation of flame response during a transverse combustion instability in a small-scale rocket engine via numerical simulation. The computation is performed in the framework of Large-Eddy Simulation with the objective to understand the physical mechanisms driving the contribution of the unsteady combustion to the unstable mode. Two simulations are considered: first, a computation of the full engine, including the injection manyfold, the 42 coaxial injectors, the combustion chamber and the outlet nozzle. Then a single injector is considered for the scrutiny of individual flame response. The analysis of the unstable transverse mode in the full configuration reveals the contribution of individual flames through a budget of acoustic energy. The single-inj.
