Soot particles were formed at 0.1MPa and 1333K using a micro-flow reactor fueled with 2% propane diluted with nitrogen, and the particle size distributions were measured. The peak of the distribution shifted to the larger particle size side as the reaction time increased. Furthermore, we tried to calculate the particle size distributions by the sectional method. The value of Ca (van der Waals enhancement factor) in the collision frequency function in the particle coagulation process was varied from 1 to 3 and compared with the measured distributions. As a result, it was found that the calculation results close to the measured distributions were obtained around Ca =2.5 to 3.0.
