Simulation of coal combustion by AUSM turbulence-chemistry char combustion model and a full two-fluid model

Kinetic Model of Coal Combustion

Fundamental Models of Coal Char Formation and Combustion

The overall objective of this project is to carry out the fundamental research needed to develop a first-generation, structure-based model of coal char formation and combustion. Current models of char combustion and carbon burnout estimate char behavior from empirical relations based on parent coal properties. With the wide range of fuels of interest to modern combustion systems (international ...

Coal Combustion and Combustion Products

The effect of model fidelity on prediction of char burnout for single-particle coal combustion

Practical simulation of industrial-scale coal combustion relies on the ability to accurately capture the dynamics of coal subprocesses while also ensuring the computational cost remains reasonable. The majority of the residence time occurs post-devolatilization, so it is of great importance that a balance between the computational efficiency and accuracy of char combustion models is carefully c...

Optimization of the Syngas Combustion Chemistry Model

Practically, an accurate combustion chemistry model is of great importance in engine simulations when it is combined with the computational fluid dynamics computations. Syngas is used as one of the fuel options in internal combustion engines. In the current work, we optimize a combustion chemistry model of syngas using machine learning algorithms. Result shows that the optimized model can achie...
