| 摘 要： | 对陶瓷蒸发腔稳定器用于模型加力燃烧室的火焰稳定进行了初步的实验研究及分析。结果表明：由于陶瓷材料的多孔性质，不仅对燃油有很强的吸附及参透能力，而且可以大在改善燃油的蒸发条件，加快化学反应速度。因此，与金属稳定器相比，陶瓷蒸发腔稳定器具有火焰稳定范围，再点火性能好及能减弱或消除振荡烧等特点。性能占明显优势，但强度可靠性有特进一步考验。 |

| Abstract: | Preliminary experimental study and analysis on flame stability of a model afterburner in which a ceramic stabilizer is used are described in this paper. It is found that the evaporation of liquid fuel can be greatly improved by utilizing strong oil absorptivity and permeability of porous ceramics. Morever, the related chemical reaction can thus be accelerated. Consequently, the ceramic flame stabilizer has advantages over metallic ones in enlarging the range of flame stabilization, enhancing reignitability, weakening oscillating combustion and etc. However, some further investigation should be concentrated on the strength and reliability of the ceramic stabilizing baffles. |
| Keywords: | Afterburning Ceramic material Flame stability Combustion stability Refractory material |
