A Cleaner Vision

Anyone who’s ever lathered up knows the dilemma. The same qualities that make surfactants — the chemical compounds in soaps, shampoos and detergents that penetrate grease, dissolve stains and make those satisfying suds in the shower — so effective as cleaners can also act as irritants. When splashed in the…

Summit Helps Forge Stronger Flights

Titanium alloys serve as cornerstone materials for the aerospace industry — stronger and lighter than steel, resistant to rust and corrosion and resilient past the melting points of most other metals. Companies such as RTX, formerly Raytheon Technologies, rely on these sturdy alloys to build such vital machinery as jet-engine turbine…

Exascale Drives Industry Innovation for a Better Future

By Caryn Meissner, ECP contributing writer   Outside the high-performance computing, or HPC, community, exascale may seem more like fodder for science fiction than a powerful tool for scientific research. Yet, when seen through the lens of real-world applications, exascale computing goes from ethereal concept to tangible reality with exceptional…

Learning With the Flow

The bigger the swirl, the bigger the problem — and the bigger the computing power needed to solve it. Computational fluid dynamics researchers have spent decades studying how liquids and gases flow in and around such machinery as airplane wings, propeller blades and jet engines in search of faster speeds…

Speeding up simulations

Artificial intelligence has transformed industrial research and development in recent decades during what scientists call "the AI revolution." The technology enables detailed simulations and high-speed modeling that can streamline the journey from drawing board to production line by speeding up or cutting out costly, time-consuming steps to a practical working…

New Deep Learning Techniques Lead to Materials Imaging Breakthrough

Supercomputers help researchers study the causes and effects—usually in that order—of complex phenomena. However, scientists occasionally need to deduce the origins of scientific phenomena based on observable results. These so-called inverse problems are notoriously difficult to solve, especially when the amount of data that must be analyzed outgrows traditional machine-learning…

Summit Fires up Predictive Breakthrough for Gas Turbines

Gas-fired turbines keep electric generators humming around the world, from power plants and factories to hospitals and universities. But the combustion process that fuels these engines comes with a billion-dollar-a-year problem: Under the wrong conditions, the resulting heat and noise can cause tremors and vibrations known as thermoacoustic oscillations, which…

Pioneering Frontier: Meeting Industry at Scale

The “Pioneering Frontier” series features stories profiling the many talented ORNL employees behind the construction and operation of the OLCF’s incoming exascale supercomputer, Frontier. The HPE Cray system is scheduled for delivery in 2021, with full user operations in 2022. When the Oak Ridge Leadership Computing Facility’s (OLCF’s) next supercomputer,…

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…

Pinnacle Engines Develops Efficient, Low-Emission Gasoline Engine Using Supercomputing

https://vimeo.com/304393904The Pinnacle Engines opposed-piston cylinder shown in three different views. Visualizations illustrate the generation of coherent flow structures and their collapse during the compression stroke, which leads to high levels of turbulence before combustion. Pinnacle Engines researchers analyzed fluid dynamics and combustion behavior to optimize the design of the combustion…

SmartTruck Steps Up Simulations for Certification by Computation

Long-haul tractor trailers, often referred to as “18-wheelers,” transport everything from household goods to supermarket foodstuffs across the United States every year. According to the Bureau of Transportation Statistics, these trucks moved more than 10 billion tons of goods—70.6 percent of the nation’s total freight shipments—in 2016. But this transport doesn’t…
