Abstract

A specially designed High Pressure Vessel and Burner and fueling system (called "doped flame") are presented in this paper. This setup allows for soot measurements in laminar diffusion flames of liquid fuel blends at elevated pressure. Fuels with two typical molecular structures, namely linear and saturated cyclic hydrocarbons, are examined in both non-oxygenated (n-hexane (C₆H₁₄) and cyclohexane (C₆H₁₂)) and oxygenated form (1-hexanol (C₆H₁₄O) and cyclohexanol (C₆H₁₂O)). All compounds are blended into n-heptane. Focus of the research is on soot volume fraction at elevated pressure in the range of 1.5-2.0bar. Sooting tendency is evaluated by means of Laser Induced Incandescence (LII) with Line of Sight Attenuation calibration (LOSA), and the data suggests that soot is more prevalent for cyclic structures relative to their linear counterparts.
