Book 2020s on e.g. interactions between acoustic waves and flames, flow dominating instability, ignition instability, flame flashback, and near-blowout-limit combustion. In turn, the book discusses in detail the fundamental mechanisms of these phenomena, and puts forward practical suggestions for future scramjet design..作者: Increment 時間: 2025-3-22 06:10 作者: Hiatus 時間: 2025-3-22 11:24
Cavity Ignition in Supersonic Flows,mixing, ignition and combustion processes inside a scramjet combustor. Current scramjets usually require flame holding devices which provide subsonic environments to facilitate flame ignition and stabilization, because the ignition delay time of hydrocarbon fuels is long relative to their residence 作者: laceration 時間: 2025-3-22 13:34 作者: 字謎游戲 時間: 2025-3-22 18:43 作者: SEVER 時間: 2025-3-22 21:19
t develops its citizens’ capacities (skills-and-competencies) for policymaking; and (b) those that do not foster such capacities, and subject policymaking to the logic of powering and regime maintenance. The three cases of policymaking show more powering than puzzling styles of policymaking; and the作者: 雄辯 時間: 2025-3-23 01:42 作者: 從容 時間: 2025-3-23 07:03 作者: animated 時間: 2025-3-23 11:02 作者: 啪心兒跳動 時間: 2025-3-23 15:33
Flame Flashback in Supersonic Flows,Non-stationary flame propagation against the incoming supersonic flow in scramjet engines has been in focus of numerous experimental and computational studies. In this chapter, we give the research work of the flame flashback phenomenon in scramjet combustor under a condition of flight Mach 4 and Mach 5.5.作者: 有機(jī)體 時間: 2025-3-23 21:34 作者: 指耕作 時間: 2025-3-24 00:35

Acoustic Oscillation in Supersonic Combustor,d, where the pressure oscillations occur, especially for the combustor with cavity. The oscillation frequency varies from hundreds of Hz to 15,000?Hz or higher. This phenomenon is called combustion instability.作者: 執(zhí) 時間: 2025-3-24 10:48 作者: Meander 時間: 2025-3-24 15:03 作者: Provenance 時間: 2025-3-24 20:50
