文摘

The flammable region of methane micro-jet flame in coflow airs was measured. OH and CH distributions of the methane micro-jet flames were obtained. The heat exchanges through different surfaces of the solid micro tube were clarified. The fuel stream in the tube is preheated by the flame through thermal interaction. The preheating effect is significant at a moderate fuel flow velocity.
