The performance of a meso-scale swirl combustor of 6 mm in diameter, 9 mm in height and having a volume of about 254 mm 3 have been experimentally investigated. The experimental analysis has been carried out in a range of mass flow rates higher than those considered in previous works. Spectrally resolved global chemiluminescence emission from the flame have been also monitored and analyzed. Results evidenced that stability limits and efficiency of the meso-combustor decreased by increasing the mass flow rates, while under lean condition the ratio of C 2 and CH global chemiluminescence intensity showed to be well correlated with the chemical efficiency.

Abstract
The performance of a meso-scale swirl combustor of 6 mm in diameter, 9 mm in height and having a volume of about 254 mm 3 have been experimentally investigated. The experimental analysis has been carried out in a range of mass flow rates higher than those considered in previous works. Spectrally resolved global chemiluminescence emission from the flame have been also monitored and analyzed. Results evidenced that stability limits and efficiency of the meso-combustor decreased by increasing the mass flow rates, while under lean condition the ratio of C 2 and CH global chemiluminescence intensity showed to be well correlated with the chemical efficiency.| File | Dimensione | Formato | |
