In this study, the flamelet/progress-variable (FPV) approach was applied to a large eddy simulation of a pulverized coal jet flame. The FPV approach considers the characteristics of the pulverized coal flame, e.g., non-adiabatic system and several ty

Pulverized coal is still found in many practical devices even though it is recognized as “dirty fuel” because of its CO2 and pollutant emissions. To overcome this problem, advanced coal utilization technologies have been developed using numerical

Boundary conditions in computational fluid dynamics significantly affect the prediction of flow field. However, the outlet boundary conditions for the continuity equation have been rarely investigated. In addition, the velocities at the outlet bounda
