Based on the constant volume combustion bomb combined with the high -speed schlieren system, the effects of initial temperature of 450 K, initial pressures and equivalence ratios on the flame instability of hydrogen-added ethanol premixed fuel were studied. The results show that the increase of Ф or P0 enhances crack and cellularity on the flame surface, and the flame instability is enhanced, and the effect of P0 on the flame instability is more significant. The flame instability was comprehensively evaluated from the aspects of hydrodynamic instability (HDI) and thermal diffusion instability (TDI), and it was found that the increase of P0 increased the hydrodynamic instability, but the thermal diffusion instability was not greatly affected by P0. In addition, under the experimental conditions, the effective Lewis number is greater than 1, and the thermal diffusion effect always suppresses the instability of the flame, so flame instability is primarily driven by the hydrodynamic effect, which can be further verified by evaluating the global growth rate of each instability parameter. Finally, the linear stability theory model was used to determine the critical condition for the instability of the premixed flame, and it was found that the critical radius of flame instability decreases and the flame instability is promoted with the increase of Ф or P0.

文章研究了初始压力(P0)和当量比(Ф)对掺氢乙醇预混燃料火焰不稳定性的影响。结果表明:增大Ф或P0会加剧火焰的表面裂纹与细胞化程度,从而增强火焰不稳定性,其中P0对火焰不稳定性的影响更显著;从流体动力学不稳定性(HDI)和热扩散不稳定性(TDI)两个方面对火焰不稳定性进行综合评估,发现增大P0,HDI增强,但TDI受P0的影响不大;此外,在实验工况下,有效Lewis数均大于1,热扩散效应始终在抑制火焰的不稳定性,因此,导致火焰不稳定的原因是流体动力学效应;利用线性稳定性理论模型确定了预混火焰发生不稳定的临界条件,发现增大Ф或P0,火焰失稳的临界半径减小,火焰不稳定性得到促进。

文章研究了初始压力(P0)和当量比(Ф)对掺氢乙醇预混燃料火焰不稳定性的影响。结果表明:增大Ф或P0会加剧火焰的表面裂纹与细胞化程度,从而增强火焰不稳定性,其中P0对火焰不稳定性的影响更显著;从流体动力学不稳定性(HDI)和热扩散不稳定性(TDI)两个方面对火焰不稳定性进行综合评估,发现增大P0,HDI增强,但TDI受P0的影响不大;此外,在实验工况下,有效Lewis数均大于1,热扩散效应始终在抑制火焰的不稳定性,因此,导致火焰不稳定的原因是流体动力学效应;利用线性稳定性理论模型确定了预混火焰发生不稳定的临界条件,发现增大Ф或P0,火焰失稳的临界半径减小,火焰不稳定性得到促进。

Based on the constant volume combustion bomb combined with the high -speed schlieren system, the effects of initial temperature of 450 K, initial pressures and equivalence ratios on the flame instability of hydrogen-added ethanol premixed fuel were studied. The results show that the increase of Ф or P0 enhances crack and cellularity on the flame surface, and the flame instability is enhanced, and the effect of P0 on the flame instability is more significant. The flame instability was comprehensively evaluated from the aspects of hydrodynamic instability (HDI) and thermal diffusion instability (TDI), and it was found that the increase of P0 increased the hydrodynamic instability, but the thermal diffusion instability was not greatly affected by P0. In addition, under the experimental conditions, the effective Lewis number is greater than 1, and the thermal diffusion effect always suppresses the instability of the flame, so flame instability is primarily driven by the hydrodynamic effect, which can be further verified by evaluating the global growth rate of each instability parameter. Finally, the linear stability theory model was used to determine the critical condition for the instability of the premixed flame, and it was found that the critical radius of flame instability decreases and the flame instability is promoted with the increase of Ф or P0.
