NETL has released the latest version of its award-winning Multiphase Flow with Interphase eXchanges (MFiX) — a computational fluid dynamics (CFD) software suite designed to shorten the time and reduce the cost associated with developing new power generation technologies.

MFiX serves as the cornerstone of NETL’s efforts in multiphase flow science (MFS) and reactor modeling, aiming to provide a deep understanding of how different phases of matter interact physically and chemically within energy systems. It is a crucial tool that helps drive engineering breakthroughs supporting U.S. economic competitiveness, national security and scientific discovery. The software currently boasts more than 9,700 registered users globally.

Building on more than 35 years of world-class multiphase flow research, MFiX allows researchers to create detailed computer models of complex multiphase systems. This capability is vital for developing new, more efficient power generation technologies.

The latest version, MFiX 25.1, enhances simulations for NETL research initiatives such as gasification and catalyst regeneration. This release introduces a new model that improves computational simulation of pyrolysis, gasification or any multiphase process where kinetics and mass transfer play a crucial role.

The new release will be used in concert with the National Lab Gasification Consortium to accelerate the maturation of mixed feed gasification.

MFS research at NETL is performed by a crosscutting team of engineers and scientists in NETL’s Computational Science and Engineering (CSE) directorate, skilled in development and application of multiphase computational fluid dynamics software and multiphase experimentation. CSE’s Multiphase Flow Team consists of dozens of DOE and contractor researchers coming together from U.S. and international multiphase flow academic and industry research programs.

NETL is a DOE national laboratory dedicated to advancing the nation’s energy future by creating innovative solutions that strengthen the security, affordability and reliability of energy systems and natural resources. With laboratories in Albany, Oregon; Morgantown, West Virginia; and Pittsburgh, Pennsylvania, NETL creates advanced energy technologies that support DOE’s mission while fostering collaborations that will lead to a resilient and abundant energy future for the nation.
