| Popis: | Experimental studies on the extinction limits and near-limits flame behaviors of premixed ethanol/air flames in a stagnation point flow were made by using an axisymmetric counter flow, twin-flame configuration, with adjustable nozzles separation distance. The extinction limits were obtained under various conditions included equivalence ratios, flame stretch rates, inlet mixture temperatures, with and without heat loss; and the flammability of ethanol was then obtained by extrapolating the extinction limits to a stretchless condition. Finally, various near-limits flame extinction phenomena were discussed. |
