It has been used for describing bubbling and circulating fluidized beds and spouted beds. MFiX calculations give transient data on the three-dimensional distribution of pressure, velocity, temperature, and species mass fractions. MFiX code is based on a generally accepted set of multiphase flow equations. The code is used as a "test-stand" for testing and developing multiphase flow constitutive equations.
NETL hosted the meeting at its Morgantown campus from August 19-20, 2013. The objective of this special two-day meeting was to develop a roadmap to address technical issues associated with the handling of non-Newtonian multiphase slurries across various applications managed by Department of Energy's Office of Environmental Management (EM). These include the Tank Farm Project and Waste Treatment & immobilization Plant (WTP) Project, which store, mobilize, and transport slurries at the Hanford Office of River Protection (ORP) in Richland, WA. Please visit the workshop page for additional details.
The Department of Energy's, National Energy Technology Laboratory (NETL) is pleased to announce the release of a multiphase flow simulation Small Scale Challenge Problem (SSCP-I) based on experimental measurements in a 3"x9"x48" fluidized bed. The purpose of SSCP-I is to improve the reliability of computational modeling of multiphase flows by validating with accurate and well defined experimental data. State-of-the-art experimental techniques will be utilized including high speed particle image velocimetry (HsPIV) for velocity measurements and high speed pressure transducers for pressure data acquisition. Data submissions will be accepted until September 30, 2013 when the experimental results will be released. Please visit the Challenge problem page for additional details.

The annual multiphase flow sciences workshop, hosted by NETL's Multiphase Flow Research Team, was held on August 16-18 in Pittsburgh, PA. Over eighty researchers from around the world attended. During the three day workshop, 40 presentations were made covering areas of interest to the multiphase community, such as fundamental multiphase model development, application of advance diagnostic tools to gas-solid flows, oxy-combustion, gasification, chemical looping, and CO2 adsorption. In keeping with the 2006 Multiphase Flow Technology Roadmap, an entire afternoon session was devoted to the quantification of uncertainty and its application to the area of multiphase flows. During the workshop, a meeting was held with researchers from Ames Lab, LLNL, Virginia Tech, and NETL's multiphase research team to discuss future collaborative work in the area of uncertainty quantification in gas-solid flows. Also, the results of the most recent NETL-PSRI multiphase Challenge Problem were presented. Feedback provided by the participants will be incorporated into the next multiphase challenge problem scheduled for 2012-2013. The 2011 multiphase workshop proceedings can be viewed at http://www.netl.doe.gov/publications/proceedings/11/mfs/index.html.
The results, to date, of NETL funded research project entitled "Development, Verification, and validation of Multiphase Models for Polydisperse Flows" being conducted by a team of researchers from University of Colorado, PSRI, Iowa State University, and Princeton University have been released and are available at http://www.psriextra.com/AR_Polydispersity_Open/ AR_Polydispersity_Open/Welcome.html .
