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.
