Advanced Computational Model for Three-Phase Slurry Reactors
View the animations above.
The main goal of this project is to develop a scientific understanding of three-phase slurry
reactors in coal conversion processes, in particular, synthetic liquid fuel production. One main
objective is to develop an advanced computational capability for predicting the transport and
processing of three-phase slurry reactors. Special attention will be given to the slurry phase
Fischer-Tropsch (F-T) processing, which provides an important route to convert coal-derived
synthesis gas to hydrocarbon fuels. The specific objective is to develop an accurate and reliable
computational model using the extended thermodynamically consistent anisotropic theories of
multiphase flows. The model will cover the relevant hydrodynamics and chemical reaction
effects including the particle collisionals, as well as the full gas/liquid-particle chemical
reactions and mechanical interactions. The effects of fluctuation energies of fluid and solid
phases and normal stress effects will also be included. Experimental verification of the
fundamental hypotheses of the model for the special case of simple shear flows is an important
part of the proposed effort.
