National Energy Technology Laboratory

NETL’s Multiphase Flow Science (MFS) group is internationally recognized as a leader in multiphase flow research and computational multiphase flow with the widely used open source MFiX Suite and strong collaborative ties with leading researchers around the world. As part of its goal to encourage multiphase flow research and promote the exchange of ideas, NETL MFS has been hosting multiphase flow workshops since 2006, which has become an annual event since 2009.  The workshop brings together international research leaders working in the area of multiphase flow science to discuss current research projects and discuss future research and development needs in the area of multiphase flow science.

The workshops provide an excellent source of information regarding the state-of-the-art in multiphase theory development, experimental techniques, mathematical models, including techniques and research in model verification, validation, and uncertainty quantification. There is a strong industrial and educational outreach emphasis, including industry participation with student presentations from a variety of U.S. universities.  Select papers from the Workshop on Multiphase Science are often included in a special issue of  Powder Technology.

2015 NETL-IWTU Fluidization Workshop

On March 19, 2015, DOE's Office of Fossil Energy (FE), Environmental Management (EM), National Energy Technology Laboratory (NETL), and Idaho National Laboratory Integrated Waste Treatment Unit (IWTU) held the NETL-IWTU Fluidization Workshop.  This workshop discussed various fluidization topics how fluidization forms the basis for many FE and EM applications.  Topics discussed included fluidization fundamentals and their applications to power plants, coal kinetics, agglomeration, filter systems, novel instrumentation, and applications of multiphase models to fluidized bed systems.


2015 NETL Workshop on Multiphase Flow Science

Dear Colleagues,


Please "SAVE THE DATE" for the U.S. Department of Energy, National Energy Technology Laboratory's (NETL) 2015 Workshop on Multiphase Flow Science.  Pending approval, this conference will be held Wednesday, August 12 through Thursday, August 13, 2015, at Lakeview Golf Resort & Spa, 150 Lakeview Drive, Morgantown, WV, 26508.

This event will brings together international leaders from industry, academia and government laboratories in the area of multiphase flow science to discuss current research projects and discuss future research and development needs in the area of Multiphase Flow Science including gas-solid, liquid-solid, gas-liquid, and gas-solid-liquid multiphase flow.   Industrial presenters are encouraged to attend and to share their experiences and specific applications in this area.

You are invited to submit an abstract (around 300 words) for a 15 minute presentation, by June 15, 2015 to  Final agenda and notification to presenters will follow by June 30, 2015 assuming conference approval.  Due to limited time slots available for presentation, the organizing committee will ask the author(s) to either make a presentation or provide a poster presentation.

The conference will cover topics in:

  • Fundamental research in multiphase flows
  • Advancements in CFD model development for multiphase flows
  • Application of multiphase CFD to industrial systems such as gasification, combustion, fossil fuel extraction and utilization, chemical processes, etc.
  • Novel measurement techniques in multiphase flows
  • Uncertainty quantification techniques in multiphase flow simulation

We are also pleased to announce that this year's conference will be held in conjunction with the NETL Advanced Gasification Workshop which is pending approval for Monday, August 10 and Tuesday, August 11, 2015 at Lakeview Golf Resort & Spa, 150 Lakeview Drive, Morgantown, WV, 26508.  Therefore, presentations dealing with multiphase flow aspects of gasification and related processes are greatly encouraged for the Multiphase Science Workshop.

The workshop attendance is by invitation only and seating will be limited. Your official invitation and registration link will be forthcoming. Please set this date aside and register promptly.  If you have any questions or require more information feel free to contact me at 304-285-4272 or
