Measurement of Laminar Flame Speeds of Dimethyl Ether-Air Mixtures at High Pressure

고압에서 DME-Air 혼합기의 화염속도 측정

Spherically expanding flames are used to measure flame speeds, which are derived the corresponding laminar flame speeds at zero stretch. Dimethyl Ether-Air mixtures at high pressure are studied over an extensive range of equivalence ratios. The classical shadowgraph technique is used to detect the reaction zone. In analytical methodology the optimization process using least mean squares is performed to extract the laminar flame speeds. Laminar flame speeds are compared with results reported in the literature.
