The U.S. Department of Energy’s National Nuclear Security Agency (DOE/NNSA) recently announced that it had chosen MIT to establish a new research center dedicated to pursuing predictive simulations of extreme environments, including those encountered during sensitive flights and atmospheric reentry. The center will be part of the fourth phase of the NNSA’s Predictive Science Academic Alliance Program (PSAAP-IV). It supports frontier research driving the predictive capabilities of high-performance computing for open science and engineering applications related to the national security mission space.
Exascale Simulation Centre for Bonded High Ent Halpy Liquid Interactions (CHEFSI) – a joint effort of the MIT Center in Computing Science and Engineering, MIT Schwarzman College of Computing, and MIT Institute (ISN) of MIT Soldier Nanotechnologies – cutting edge edge ascu skull supercott and simulation edge ascu skull supercontrat and neighboring edge asstel and neighboring edge assma interact how hot, moving fast gaseous and solid materials. Understanding these extreme environments is characterized by temperatures above 1,500 degrees Celsius and high speeds at Mach 25, and the impact on vehicles is central to national security, space exploration and the development of advanced thermal protection systems.
“Chefsi will help ensure that the US remains at the forefront of scientific innovation by leveraging MIT’s deep strengths in predictive modeling, high-performance computing and STEM education.” “The Center’s special connection between national security and advanced technology exemplifies MIT’s commitment to advance research with a wide range of social interests.”
Chefsi is one of five new forecast simulation centres announced by the NNSA as part of a program that is expected to provide up to $17.5 million to each center over five years.
Chefsi’s research aims to capture detailed simulations of high-ent halpy gas flows and models of the chemical, thermal and mechanical behavior of solid materials, as well as phenomena such as oxidation, nitriding, ablation, fractures, and more. A carefully designed and experimental-validated advanced computational models can address the limitations of flight testing by providing important insights into material performance and impairments.
“By integrating high-fidelity physics models with artificial intelligence-based surrogate models, experimental verification, and cutting-edge exuspale calculators, Chefsi can help you understand and predict how a thermal protection system is implemented under the most demanding conditions encountered in engineering systems,” Chefsi. “This knowledge will help design resilient systems for applications ranging from reusable spacecraft to hypersensitivity vehicles.”
Radovitzky has joined the Center’s leadership team, joined by Youssef Marzouk and The Breene M. Kerr (1951) Professor of Aerospace Space and Space (CCSE), co-director of MIT Computational Science and Engineering (CCSE), who has recently been named associate dean of MIT Schwarzman College of Computing. Nicholas Haddyconstantineu, Professor of Mechanical Engineering and Co-Director of CCSE, Quentin Berg (1937), will serve as assistant director. Co-investigators at the Center include MIT faculty in the departments of aviation and astronauts, electrical and computer science, materials science and engineering, mathematics and mechanical engineering. Franklin Hadley will lead the operation of the Center with management and finances under the scope of Joshua Friedman. Hadley and Friedman are both members of the ISN Headquarters team.
Chefsi hopes to work extensively with the DOE/NNSA National Laboratories, including Lawrence Livermore National Laboratory, Los Alamos National Laboratory, and Sandia National Laboratories.
