Texte intégralEnvironmental restrictions tackle the reduction of the use of primary sources of energy motivating research to advance towards upgraded technologies. Alongside with these efforts, reliability and performance need to be ensured, especially for detrimental conditions of pressure and temperature, i.e. high altitude. In gas turbine engines, both these elements are crucial to offer products that fit to both the needs and expectations set by the present scenario. Ignition is a multiphase process constituted by several phases and events that span a diversified range of characteristic time scales. The numerical resolution of the early ignition phase, for which fine and detailed information is lacking, is investigated in this study. The efficiency of the igniter is estimated through calorimetry in pure air, which shows that variations of initial pressure have an influence on efficiency. The same investigation revealed that temperature (20° C; - 20°C) has a negligible effect. Physical properties of the kernel in terms of volume, surface, projection surface, radius of the arc channel in the cavity, are estimated adopting different optical diagnostics, including schlieren and shadowgraphy imaging at 1 MHz. Calculations are done to obtain a temporal evolution during energy depositing time (130 μs). An effect of initial pressure is observed on kernel properties such that reducing the initial pressure, kernel volume increases. Furthermore, filtered direct visualizations of the igniter cavity show that an effect of pressure is discerned from 20 μs. Kernel size is also measured for methane premixed mixtures of different equivalence ratios. This is intended to determine the influence of composition variation with respect to a reference case in pure N2 which is compared to measurements in gaseous premixed mixtures (both of inert CH4 / N2 and reactive CH4 / O2 / N2 nature). A comparison between inert and reactive cases exposes active combustion reactions already during energy deposition. To investigate the exposure to real life environment elements, the impact of a transverse flow at ambient conditions is studied in a wind tunnel. This was adapted to simulate the combined effect of a transverse flow and cooling air spilled from the liner that the igniter is exposed to by being mounted in a sleeve. The effect of the sleeve on kernel projection is investigated, which reveales an impact on projection and kernel deformation depending on the imposed velocity. The generation of the kernel is examined in a reactive premixed swirled mixture at 0.45 and 1 bar. The velocity field have been studied beforehand by PIV to know the velocity in the vicinity of the igniter and in the spatial domain where the kernel is projected. Three velocity conditions are retained to perform the discharge. Initial pressure is observed to influence the deformation the kernel undergoes depending on initial velocity. At 1 bar, the kernel appears to be preserved for longer. A secondary effect of equivalence ratio is found. The existing model of Taylor-Sedov is tested to predict kernel properties and compare them to experimental measurements. A preliminary study is performed to explore the interaction between the kernel and a spray at 0.45 bar and 1 bar. High magnification shadowgraphy is used to run statistics on a spatial window of 2 x 2 cm where droplets are observed impinging on the electrodes. Properties variations are detected depending on the synchronization with the discharge. Schlieren visualizations are further performed to observe phenomena to qualitatively explore the dynamics appearing in a time window of 1 ms
