The present study makes use of the adjoint modes of the Linearized Reactive Flow (LRF) equations to investigate the Intrinsic Thermoacoustic (ITA) feedback loop of a laminar premixed slit flame. The analysis shows that the ITA feedback loop is closed

This study performs a linear analysis of a turbulent reacting methane-air jet flame, with the goal of predicting the response of the reacting flow to upstream acoustic actuation. Accounting for heat release fluctuations is a vital component when inve

International audience; A non-modal linear hydrodynamic stability analysis of ablation waves is carried out for the firsttime. This analysis is performed for unsteady self-similar solutions in slab symmetry of theEuler equations with nonlinear heat c

Ablation waves form when a dense medium is suddenly exposed to a strong irradiation flux. A forerunning shock front propagates inside the dense medium, followed by an ablation front which corresponds to the superposition of the foot of a heat front a

International audience; Fast transient growth of hydrodynamic perturbations due to non-modal effects is shown to be possible in an ablation flow relevant to inertial confinement fusion (ICF). Likely to arise in capsule ablators with material inhomoge
