Abstract
Soot particles are combustion derived agglomerates of carbonaceous primary particles that are small enough to stay suspended in the atmosphere. Despite the soot particles role in health and environmental issues, the corresponding formation mechanisms are still poorly known. This work presents measurement results of the soot volume fraction and temperature fields at laminar non-premixed flames. The two-colour pyrometry method is used to obtain the temperature field and the light extinction method the soot volume fraction data. The experiments involved the reconstruction and adaption of a classical non-premixed burner used in previous works. The obtained results are compared to previous works in similar flames exhibiting an agreement that lies within the experimental uncertainty.
