A numerical model for combustion process of single coal particle in hot gas

고온 유동장 내 석탄 단입자 연소과정의 특성화를 위한 수치적 연구

With the experiment observation of single particle combustion, this model is built for the numerical analysis of the process. It's about the single coal particle combustion process under different conditions with reasonable assumptions. The model can express the mass, radius, density, temperature changing with different particle sizes, oxygen concentration and gas temperature. It also includes the flame sizes change in different condition and the diffusion of each species. The result shows the characters of the combustion.
