MIT uruchamia nowe centrum badawcze w celu ulepszenia symulacji ekstremalnych środowisk

In an exciting development in the world of high-performance computing, the U.S. Department of Energy’s National Nuclear Security Administration (DOE/NNSA) has chosen the prestigious Massachusetts Institute of Technology (MIT) to spearhead a groundbreaking research initiative. This new venture, known as the Center for the Exascale Simulation of Coupled High-Enthalpy Fluid–Solid Interactions (CHEFSI), will be an integral part of the fourth phase of the Predictive Science Academic Alliance Program (PSAAP-IV).

Pushing Computing Boundaries & Fostering Multidisciplinary Collaboration

CHEFSI is set on revolutionizing the capabilities of computational science by harnessing the power of exascale supercomputers alongside cutting-edge algorithms to simulate how materials behave when subjected to severe conditions – think hypersonic flight and atmospheric re-entry. Gaining a deeper understanding of such interactions between high-temperature gases and solid materials holds key implications for areas as pivotal as national defense, space exploration, and thermal protection systems.

In addition, this initiative embodies a monumental collaboration effort between a number of MIT entities, including the Center for Computational Science and Engineering, the Schwarzman College of Computing, i Institute for Soldier Nanotechnologies (ISN). With a blend of expertise from computational science, engineering, and materials research, it’s a fair bet to say that CHEFSI is well-placed to emerge as a national cornerstone for predictive modeling of extreme physical environments.

Key Objectives & Forward Momentum

CHEFSI’s priorities go beyond science advancement. Speaking about the endeavor, MIT’s vice president for research, Ian A. Waitz, voiced that the center will channel MIT’s significant strengths in predictive modeling, high-performance computing, and STEM education to bolster the United States’ position at the international forefront of scientific and tech innovation. Plus, it aligns perfectly with MIT’s own mission to propel research that contributes significantly to the greater societal good, with particular emphasis on national security and advanced technologies.

On the research front, CHEFSI plans to connect simulations of high-enthalpy gas flows with models analyzing solid materials’ chemical, thermal, and mechanical behaviors – this unified approach aims to encapsulate complex behaviors such as ablation, oxidation, nitridation, and material fracture. These insights can serve as an antidote to the limitations of traditional flight testing, offering a refined understanding of how different materials perform, and fail, under extreme duress.

The leadership team behind this ambitious project includes Raúl Radovitzky, the Jerome C. Hunsaker Professor of Aeronautics and Astronautics and associate director of the ISN, Youssef Marzouk, co-director of the Center for Computational Science and Engineering and associate dean of the Schwarzman College of Computing and Nicolas Hadjiconstantinou, co-director of CCSE and a professor of mechanical engineering. All these brilliant minds will be collaborating with a multidisciplinary team of faculty members from departments such as Aeronautics and Astronautics, Electrical Engineering and Computer Science, Materials Science and Engineering, Mathematics, and Mechanical Engineering.

Beyond research, CHEFSI plans to educate the coming generation by providing immersive research opportunities for graduate students and post-doc researchers. This will be facilitated through collaborations with national laboratories such as Lawrence Livermore, Los Alamos, and Sandia, giving students a chance to be part of groundbreaking research while contributing to national security objectives.

Investments and Future Prospects

As one of five new Predictive Simulation Centers selected by the NNSA, CHEFSI is expected to see a generous investment in the coming years – up to $17.5 million over five years. The endgame? To further its mission to create and validate high-fidelity computational models using a blend of experimental data, AI-driven surrogate modeling techniques and yes, high-fidelity physics models alongside AI-based surrogate models.

“By merging these, along with experimental validation and tadah – the state-of-the-art exascale computational tools, CHEFSI will help propel our understanding and predict how thermal protection systems perform under some of the toughest conditions encountered in engineering systems,” says an exuberant Radovitzky. It’s safe to say that the knowledge garnered will play a pivotal role in designing resilient systems, impacting a myriad of applications – from reusable spacecraft to hypersonic vehicles.
