Using state-of-the-art computational tools developed by the Exascale Computing Project and the Nuclear Energy Advanced Modeling and Simulation Program on leadership-class computing facilities, this team sets out to use Computational Fluid Dynamics (CFD) to accurately predict turbulent fluid flow and heat transfer phenomena in a wide range of nuclear power applications. 

The goal of this project is to advance the DOE’s simulation capabilities in important carbon-free energy sectors, including nuclear, fusion, and wind. 

The successful outcome of this research will achieve new scientific outcomes that demonstrate the latest potential for HPC, simulation, and AI to hyper-enable engineers to solve humanity's largest challenges, and the business implications of our success in this effort are represented by the $30 trillion opportunity described above.

This research aims to address this long-standing issue through first-principles simulations, focusing on the prospects of long-lived hypermassive neutron stars (HMNSs) as potential engines for short GRBs (sGRBs). 

The impact of the project will help to develop, implement, and test a platform to assess host-pathogen molecular interactions, adaptation to hosts and host shifts, and coevolution between hosts and pathogens.

The enhanced understanding of the physics and the ML-based models developed during this project will help improve design, optimization and safety of advanced nuclear reactors and energy systems.

Results from this work will be included in a V&V database for future validation of HTGR simulation codes and could be used to improve the sub-grid scale models in low-order codes.

The results from this project will advance the development of carbon capture technologies essential for mitigating greenhouse gas emissions impacts on health, the economy, and the environment.

The simulations in this project will provide a first-ever view into the changes to the microstructure of iron as it goes through phase transformation and extreme deformation, detail at the atomic level directly comparable to the experimental X-ray absorption data and allowing a deep understanding of iron’s behavior under these extraordinary conditions.

The simulations in this project will be performed with both Nek5000 and NekRS expanding their application to the Research Reactor Conversion Program.

To resolve the difference between lattice and data-driven theory values, the project aims to compute the hadronic contributions at the sub-percent level, and ultimately to reach the expected precision of the experiment, at the one-to-two-permille level.

This project builds upon the success of earlier INCITE awards that explored astrophysical thermonuclear explosions, as the researchers greatly expand their work to model thermonuclear flame propagation across the surface of a neutron star.

The goals of this INCITE project are to design compressive pathways towards synthesis of elusive and long-sought post-diamond BC8 phase of carbon; uncover kinetics effects in phase transformations to BC8 phase from diamond and amorphous carbon in explicit, billion atom, double-shock simulations at micrometer and nanosecond time scales.

A current goal for the aircraft industry is to unambiguously demonstrate consistently accurate predictive computations of high-lift flows. If this objective can be realized, computations may facilitate a simulation-based approach to certification, thereby significantly reducing the cost of bringing a new aircraft to market while continuing to meet strict safety guidelines. 

This team will deploy new state-of-the-art machine learning (ML) methods to construct reliable and accurate force fields, trained on accurate quantum electronic structure (DFT) calculations and perform record-scale and -speed MD simulations of battery and catalytic interfaces.

This team set out to perform an unprecedented pair of decadal-scale climate simulations with an atmospheric grid spacing of 3.25 km. 

The team will use a sizeable INCITE allocation to explore efficient alternatives for transformer models for language modeling.

This project will calculate the 3D structures of the pion and kaon, which are the Nambu-Goldstone bosons of the strong force that bind nuclei together, to advance our understanding of the strong interaction and confinement of quarks and gluons inside hadrons.

This project will scale up the training of foundation models to the largest available chemical libraries to advance the design of new electrolytes for energy storage and energy conversion applications.

This project uses a new performance-portable version of the Athena++ astrophysical MHD code to perform the first calculations of radiation-dominated accretion on black holes using full transport methods and realistic opacities.
