| Outline of Final Research Achievements |
A new analytical method for compressible particle flow with reactive particles was developed by combining numerical fluid dynamics and the discrete element method, and particle behavior was investigated for a problem involving the dispersion of deposited particles due to shock waves. A new analytical model was developed to track the particle behavior in the particle-thin region, which cannot be captured by the conventional two-fluid model based analytical method for the target problem. Numerical analysis of shock wave-induced combustion of sedimentary coal dust was also performed, and the validity of this method for polydisperse combustion problems was demonstrated through comparison with experimental data. The structure of the combustion wave during steady-state propagation was also clarified from the analytical results.
