The oxidation rate of diesel engine soot particles has been measured experimentally over a range of gas temperatures (1650-1820 K) and oxygen partial pressures (0.01-0.05 atm). Soot particles from the exhaust of a running diesel engine were oxidized in the post-flame gases from a premixed burner. Measurements made at different heights above the flame included the particle size distribution and velocity, the gas temperature and the oxygen concentration. The results showed that the measured oxidation rates were between the values predicted by the Nagle-Strickland-Constable formula and those predicted by the Lee formula. The experimental results from the present study were combined with those of other experimenters and used to modify the Nagle-Strickland-Constable and Lee formulae in an effort to improve their predictive capability.
