Blake, T. R.

This was the third quarter in the second year of research to develop and apply computer codes, based upon continuum theories of multiphase flows, to the performance of fluidized bed and entrained flow coal gasification reactors. Research was active in several areas. The research on the fluidized bed model was directed to the continued development of the chemistry for steam-oxygen gasification and to the incorporation of that chemistry into the numerical formulation. In addition, theoretical studies were continued or initiated on compressibility effects in fluidized beds, mechanical interaction functions, constitutive relationships and particle size effects. The work on the entrained flow model included a continued formulation of the equations for turbulent gas-solid particle motion, the examination of chemical kinetics and the successful completion of a model computer code appropriate to representing transient entrained flows. This latter code, which involves a finite element-finite difference formulation has been applied to study swirling flows of a compressible viscous gas.
