A COMPUTATIONAL STUDY OF DEVOLATILIZATION AND KINETICS IN ENTRAINED FLOW COAL GASIFICATION
Computational fluid dynamics (CFD) modeling is an integral part of the design cycle of modern entrained flow gasifiers. Gasification modeling considers an interacting multi-phase media in a turbulent environment. Several gasification sub-models have been developed and validated over the last thirty …

Multiscale CFD simulations of entrained flow gasification
… it was practical to apply CFD models. Moreover, gasification CFD models developed over the years may have lacked accuracy or have not been tested over a wide range of operating conditions, gasifier geometries and feedstock compositions. One reason behind this shortcoming is the failure to …

Comprehensive Modeling and Numerical Investigation of Entrained-Flow Coal Gasifiers
Numerical simulations of coal gasification process inside a generic 2-stage entrainedflow gasifier are carried out using the commercial CFD solver ANSYS/FLUENT. The 3-D Navier-Stokes equations and eight species transport equations are solved with three heterogeneous global reactions, three …
