| 英文摘要 | Although research interest in pressure gain combustion remains high, information on the deflagration-to-detonation transition (DDT) process in actual multiple-cycle pulse detonation combustors is sparse, especially in terms of initial pressure studies, a crucial parameter in design and operation of such combustors. To develop microscale detonation combustion technology and gain a better understanding of the impact of initial pressure, an experimental study on flame acceleration of hydrogen-oxygen premixed gas is conducted using a micro spiral channel with a Tesla turbine at the outlet, which can realize precise initial pressure regulation in an open-ended pulse detonation combustor. The initial pressure consists of turbine wind pressure (p(T)) and intake residual pressure (p(ir)). p(T) increases the back pressure at combustor's outlet, and p(ir) is derived from the channel static pressure and flow velocity during the gas intake phase by bringing the ignition timing close to the moment when the solenoid valve closes. The flames are recorded by high-speed photography and the flame propagation characteristics under different initial pressures are compared. Results demonstrate that different combinations of p(ir) and p(T) yield three distinct DDT modes (Mode1: low p(ir) boolean AND low p(T); Mode2: low p(ir) boolean AND high p(T); Mode3: high p(ir) boolean AND any p(T)), with p(ir) significantly outperforming p(T) in shortening DDT distance (L-DDT, Mode3 < Mode2 < Mode1) and mitigating the detonation wave velocity deficit (DWVD, Mode3 < Mode2 <= Mode1). High-pressure intake and timely ignition after valve closure (to trigger Mode3) is a very efficient way to generate detonation waves, which could be an ideal operation method for microscale pulse-detonation-based devices with hydrogen energy. |
