The aim of the Ph-D thesis is to study ignition mechanisms of a flame kernel in laminar and turbulent flows. First, a preliminary study is devoted to the analysis of the laser-induced spark ignition system and to the study of the flame kernel initiation in premixed laminar flow. Then, the study of the ignition is performed in turbulent premixed flow, to highlight the influence of velocity turbulent fluctuations on the flame kernel initiation. Finally, in turbulent non-premixed flows, the effect of the local and instantaneous mixture fraction on the flame kernel initiation and development is analyzed.L'objectif de la thèse est d'étudier les mécanismes d'allumage d'un noyau de flamme en écoulements laminaires et turbulents.
