| 内容記述 | Research on power generation or propulsive devices based on detonation gained interest in the past two decades. Indeed, detonation-based devices, such as rotating detonation engines （RDE） or pulse detonation engines （PDE）, may confer a thermal efficiency of gain up to 15 % compared to conventional thermal engines. For this reason, RDE and PDE are studied worldwide, but mostly with gaseous fuel and oxidizer injection. However, under the constraint of practical applications such as engine size limitation, using liquid fuel to increase the energy density is expected. A liquid injection adds complexity to an already challenging problem. Past studies on detonation through multi-phase medium encounter complications such as droplet size effects, partial vaporization, poor fuel/oxidizer mixing, and a complex detonation front structure. Therefore, in order to achieve a stable and reliable liquid detonation engine, it is necessary to understand the mechanism occurring during the detonation process. Those mechanisms are still poorly understood due to the relatively small number of experimental or numerical studies on the subject. This thesis aims to clarify these lacunae by studying the droplet effects on detonation propagation. The analysis is divided into two parts: the first is the validation and investigation of detonation propagation through mono-dispersed and poly-dispersed droplet clouds of n-heptane in a tube. The second part is the numerical analysis of a kerosene/air/hydrogen RDE to evaluate the performance and understand the behavior of the detonation through a multiphase cross-flow injection. | |||||||
