Numerical Simulation of Pulverized Coal Combustion and Gasification

Abstract

Numerical simulation techniques concerning pulverized coal combustion and gasification have been continuously developed and applied to a wide range of reactor scales. Very recently, unsteady large-scale simulations become to be paid attention to with the computer hardware development. This paper describes the recent development of the unsteady large-scale simulations of pulverized coal combustion and gasification on the demonstration-scale reactors by means of large-eddy simulation (LES). In addition, recent sub model developments for coal combustion and gasification are also reviewed and assessed in terms of the model accuracy.
