Computer modeling of coal gasification reactors. Quarterly technical progress report, July 1, 1977--September 30, 1977
The research on the fluidized bed computer code included the modification of the code to treat axisymmetric geometries. Test calculations were performed and studies were initiated to calculate the relative behavior of planar and axisymmetric bubble evolution. Analytical and numerical formulations of fluidized bed chemistry and hydrodynamics were examined, for the purposes of extending and improving the fluidized bed model. Specific numerical calculations of solids convection, with application to the synthane gasifier, were performed as part of a continuing investigation of jet and bubble formation at the distributor plate. The work on the entrained flow computer model involved the extension of this code to treat flows in three spatial dimensions. Subroutines in the new code were tested and calculations were initiated to simulate the gas dynamics and solid particle flows in a combustion stage of a two stage gasifier configuration. The formulation of a kinetics model for pulverized coal particles was continued. A model study of the relative influences of oxidation and gasification reactions upon mass loss from a carbon particle was completed. Included in this report as an appendix is ''A Theoretical Study of Burning Carbon Particles'' by P.A. Libby.
