Researchers at the Georgia Institute of Technology have completed the largest direct numerical simulation (DNS) of three-dimensional turbulence to date, using 35 trillion grid points. This work was made possible by the Frontier supercomputer at the Department of Energy’s Oak Ridge National Laboratory, which offers exascale computing power capable of performing over a billion billion calculations per second.
The simulation provides unprecedented detail in modeling turbulent flows, a complex phenomenon that occurs in many natural and industrial processes. By leveraging Frontier’s advanced capabilities, the team was able to explore turbulence dynamics at a scale not previously achievable.
**Why this matters**
Turbulence plays a critical role in fields such as weather forecasting, aerospace engineering, and energy production. Accurate simulations help improve the understanding of turbulent behavior, leading to better predictive models and more efficient designs. Achieving this level of resolution sets a new benchmark for computational fluid dynamics and demonstrates the potential of exascale computing in tackling complex scientific challenges.
