Abstract
This paper presented experimental investigation on effects of pressure on laminar flame speed and Markstein length of typical syngas in a recently developed dual-chambered, pressure-release type high-pressure combustion apparatus. The results show that the laminar flame speed of syngas firstly increases with the equivalence and then begins to decrease with further increasing equivalence ratio. It decreases with the increase of pressure. The laminar flame speed predicted by Davis and Sun mechanisms was in agreement with the experimental results at elevated pressures. Markstein length increases with equivalence ratio and decreases with the increase of pressure.
