| Outline of Final Research Achievements |
A model that can reproduce the phenomena of soot formation from the volatile matter evolved from solid particles for the unsteady numerical simulation of solid combustion field has been developed. 13 species including tar are postulated as volatile matter. The model can take into account the effect of particle heating rate on the amount of volatile matter and its evolution rate. The large eddy simulation of the 4 kW coal combustion filed with the developed model was conducted. As a result, the tendency of the soot volume fraction distribution predicted by the numerical simulation was consistent with that obtained by the optical measurement. The high accuracy of the developed model was validated by the comparison.
