Planning for a Smooth Landing on Mars

A U.S. mission to land astronauts on the surface of Mars will be unlike any other extraterrestrial landing ever undertaken by NASA. Although the space agency has successfully landed nine robotic missions on Mars since its first surface missions in 1976 with the Viking Project, safely bringing humans to Mars…

COVID-19 in the Classroom: Simulating the Spread

A team led by Rao Kotamarthi at the US Department of Energy’s (DOE’s) Argonne National Laboratory (Argonne) is using supercomputers at DOE’s Oak Ridge National Laboratory (ORNL) to study how aerosol viral particles are distributed in a ventilated classroom. Using ORNL’s Summit, the nation’s fastest supercomputer, the team simulated the…

Titan Study Takes Jet Turbine Design to New Heights

Simulations performed on Oak Ridge National Laboratory’s (ORNL’s) Titan supercomputer could clear the runway for more efficient jet-engine turbines and help set a new benchmark for turbine design. The study by an international team of scientists modeled air flow over a 3D turbine blade using the computational power of Titan,…

GPUs Power GE Code at OLCF Hackathons

The ability to simulate turbulent phenomena using high-performance computing (HPC) can provide industry with important insights for efficient engine design. Second only to the ability to perform these critical simulations is the speed at which they run. If a company can run a model more quickly, the number of possible…

New Boeing Method Accelerates Turbulence Modeling Uncertainty Analysis

A simulation of a physical wind tunnel airplane model (the NASA Common Research Model), widely used for CFD benchmarking and analysis. Boeing researchers recently used OLCF resources to perform simulations that would aid them in identifying and reducing uncertainty in a computational turbulence model called the Spalart–Allmaras model. Quantifying the…

3-D Models Help Scientists Gauge Flood Impact

Heavy rainfall can cause rivers and drainage systems to overflow or dams to break, leading to flood events that bring damage to property and road systems as well potential loss of human life. One such event in 2008 cost $10 billion in damages for the entire state of Iowa. After…

Streamlining Accelerated Computing for Industry

Scientists and engineers striving to create the next machine-age marvel—whether it be a more aerodynamic rocket, a faster race car, or a higher-efficiency jet engine—depend on reliable analysis and feedback to improve their designs. Building and testing physical prototypes of complex machines can be time-consuming and costly and can provide…
