Title: Final report for the ASC gas-powder two-phase flow modeling project AD2006-09.

Abstract

This report documents activities performed in FY2006 under the ''Gas-Powder Two-Phase Flow Modeling Project'', ASC project AD2006-09. Sandia has a need to understand phenomena related to the transport of powders in systems. This report documents a modeling strategy inspired by powder transport experiments conducted at Sandia in 2002. A baseline gas-powder two-phase flow model, developed under a companion PEM project and implemented into the Sierra code FUEGO, is presented and discussed here. This report also documents a number of computational tests that were conducted to evaluate the accuracy and robustness of the new model. Although considerable progress was made in implementing the complex two-phase flow model, this project has identified two important areas that need further attention. These include the need to compute robust compressible flow solutions for Mach numbers exceeding 0.35 and the need to improve conservation of mass for the powder phase. Recommendations for future work in the area of gas-powder two-phase flow are provided.

  • A two-dimensional, numerical, mathematical model has been developed to predict methane influx into coal mines under a variety of mining conditions. A set of time-dependent, partial differential equations for two-phase Darcy flow in a porous medium was developed. One-dimensional models were expanded to two-dimensional models by appropriate geometric modification of the basic equation set. Numerical solutions were obtained with an implicit method-of-lines technique. Boundary conditions corresponding to the appropriate mining system can be selected. The model and solution procedure are coded in a structured dialect of FORTRAN and a preprocessor is included for adaptation to popular computer systems. To obtainmore » data for comparison with the model, methane measurements were made in three coal mines in the Eastern United States to encompass a range of gas contents, porosities, permeabilities, coal rank, and mining methods. Volume I contains the final report and summary, methane measurement data, mathematical components, and simulation demonstrations.« less

  • A summary is given of the work carried out under the LDRD project 09-ERD-025 entitled Scrape-Off-Layer Flow Studies in Tokamaks. This project has lead to implementation of the new prototype Fourier Transform Spectrometer edge plasma flow diagnostic on the DIII-D National Fusion Facility at General Atomics, acquisition of carbon impurity concentration and flow data, and demonstration that the resulting data compare reasonably well with LLNL's edge plasma transport code UEDGE. Details of the work are contained in attached published papers, while the most recent results that are being written-up for publication are summarized in the report. Boundary plasma flows inmore » tokamak fusion devices are key in determining the distribution of fuel and impurity ions, with tritium build-up in the walls an especially critical operational issue. The intrusion of impurity ions to the hot plasma core region can result in serious energy-loss owing to line radiation. However, flow diagnostic capability has been severely limited in fusion-relevant hot edge plasmas where Langmuir-type probes cannot withstand the high heat flux and traditional Doppler spectroscopy has limited resolution and signal strength. Thus, new edge plasma flow diagnostic capabilities need to be developed that can be used in existing and future devices such as ITER. The understanding of such flows requires simulation with 2-dimensional transport codes owing to the geometrical complexity of the edge region in contact with material surfaces and the large number of interaction physical processes including plasma flow along and across the magnetic field, and coupling between impurity and neutral species. The characteristics of edge plasma flows are substantially affected by cross-magnetic-field drifts (ExB/B{sup 2} and BxVB/B{sup 2}), which are known to introduce substantial convergence difficulty for some cases. It is important that these difficulties be overcome so that drifts can be included in transport models, both for validation with existing data and for projection to future devices.« less
  • GRI held a workshop on April 27, 1987 to discuss state-of-the-art technology used to simulate reservoir behavior and to investigate planning strategy for future GRI research activities in reservoir modeling, specifically the complexities of modeling multi-phase flow. During the morning session GRI contractors involved with reservoir simulators and related research made brief presentations on their research activities. The afternoon session was an informal group discussion designed to address future research needs. The summary prepared by each presenter is provided, along with presentation material from slides and/or overheads. Written comments by attendees about the workshop are included.
  • Described in this document are models for the thermal-hydraulic analysis of pressurized water reactor bottom reflooding. The solid/flow conservation equations are presented in forms compatible with the Modular Modeling System (MMS). Based on the analytical models, two stand-alone MMS modules were developed. These modules are the stand-alone single power region forced reflood module (XF) and the stand-alone single power region gravity reflood module (XG). The modules were validated against the experiment with satisfactory results. The computer CPU time on the Cyber 77 was about one-fourth of the real reflood duration for the forced reflood module XF. For the gravity refloodmore » module, XG, the computer CPU time was roughly equal to the real reflood duration.« less
