The work carried out under this Field Work Proposal (FWP) will contribute directly to improving the continuum computational models used by the gasification group at the National Energy Technology Laboratory (NETL) for system design and analysis. The modeling capabilities will be extended to handle variable-density and variable-size reacting particles in turbulent flow using state-of-the-art mathematical modeling tools.
The project will further the present understanding of circulating fluidized beds from the conceptual standpoint of kinetic theory. The primary purpose is to provide a theoretical underpinning for the construction of computer codes to better understand and predict multiphase flow behavior in circulating fluidized beds and, in particular, to provide theoretical estimates for the transport coefficient analogues that parameterize the computer simulations.
This project will reduce design time for gasification combustion and supporting systems, which will result in lower capital costs for future facilities.
