Combustion and percolative fragmentation of carbons

The combustion of a carbon particle under control of both chemical kinetic and intraparticle diffusion is analyzed. Percolative fragmentation is taken into account to express carbon combustion efficiency. Continuous and discrete models are considered and their advantages and drawbacks examined. A co...

More Information
Summary:The combustion of a carbon particle under control of both chemical kinetic and intraparticle diffusion is analyzed. Percolative fragmentation is taken into account to express carbon combustion efficiency. Continuous and discrete models are considered and their advantages and drawbacks examined. A combustion model that couples features of continuous and of discrete models is proposed. Results and example calculations are presented.
