MFS research at NETL is performed by a crosscutting team of engineers and scientists in NETL’s Computational Science and Engineering Directorate (CSE), skilled in development and application of multiphase computational fluid dynamics software and multiphase experimentation. CSE’s Multiphase Flow Team consists of 30 DOE and contractor researchers coming together from U.S. and International multiphase flow academic and industry research programs.



The MFS program provides a broad range of software tools, research laboratory capabilities, high fidelity data, and a product support forum to serve the program’s stakeholders and benefit the multiphase flow research community

MFS flagship, open-source suite of multiphase, computational fluid dynamics software

A high-performance, massively parallel, machine agnostic multiphase flow code for the exascale computing era

Chemistry management software focused on computational modeling of reacting systems

Flexible graphical programming library for development of software process workflows

Multiphase flow laboratory for high-fidelity data supporting model development and code validation

Cross-platform application for tracking objects in videos, image stacks, or files that contain object positions

Interact with and learn from MFS developers, researchers and the stakeholder community online

Research + Publications

MFS research at NETL is funded by several U.S. Department of Energy programs, with primary support coming from DOE’s Office of Fossil Energy and Carbon Management (FECM). MFS tools and capabilities support FE’s mission to ensure the nation can rely on traditional energy resources for clean energy while enhancing environmental protection. The MFS team works to improve the understanding of both fundamental multiphase physics and performance of multiphase devices that underpin exiting and new technologies for this effort


Bringing together international leaders from industry, academia, and government laboratories to exchange ideas and progress in advancing the use of physics-based multiphase simulations to overcome technical barriers encountered in the development of highly efficient, environmentally acceptable energy, environmental and industrial technologies and processes
