It is suggested that theprocessbe started as soon as possible.Area of Interest 11 - Coarse Grid ModelingTwo-fluid model simulations of chemically reacting dense gas-solids systemsrequire a large number of computational cells to accurately resolve thehydrodynamic features. However, such an approach for large scale systemse.g.,the transport gasifier at the PSDF (http://psdf.southernco.com/index.html)isnot practical with today?s computers. Recent work has focused on thedevelopment of a sub-grid scale model that would allow a modeler to use acoarse grid with a sub-grid scale model for the gas-solids drag to accountforthe loss of hydrodynamic information due to the coarse grid. This approachwasdeveloped by considering a single representative computational cell withinanoverall two-dimensional simulation. This cell is then resolved with a veryfinegrid with periodic boundary conditions. Simulations of this cell are thenperformed and statistical data is collected to show the effect of gridresolution on the gas-solids drag coefficient.To use this approach for simulations on a scale similar to that of thetransport gasifier at PSDF, or larger, the earlier two-dimensional workwouldneed to be extended to three-dimensions to develop reliable coarse-grainedforms of the two-fluid models and boundary conditions that average over theeffects of small scale fluctuations, e.g. with filter lengths of 100 to1000particle diameters and commensurate temporal filters. The attributes ofsuchcoarse-grained models should lead to grid-size independent solutions withcoarser grids and larger time steps, and these solutions should representaccurately the macro-scale flow characteristics obtained in highly resolved(fine grid) two-fluid model simulations. The 2-D sub-grid modelconstitutiveequations and methodologies are available from the work referenced at thebottom.DOE is interested in research that will extend the 2-D sub-grid concept tothree-dimensions and demonstrate the coarse-grained forms for various termsinthe two-fluid model, and develop fundamentally based filter-size dependentclosed form closures for them or devise a validated computational approachtodetermine them. The methodology is as important as the final closed formequations, as two-fluid models continue to evolve and one should be able toadapt the methods developed in this research to improved two-fluid modelsasand when they become available. Sub-grid model validation will be done withfine grid comparisons to be done by the developer for simpleconfigurations.Large scale validation of such coarse-grained equations will bedemonstratedthrough comparison with highly resolved (fine grid) simulations of thestartingtwo-fluid model equations on meaningful test problems by NETL.To link to the master announcement DE-PS26-05NT42472-00, please click thefollowing link:https://e-center.doe.gov/iips/faopor.nsf/UNID/AFDC3E3018D30D1C8525700C005DB010?OpenDocument
