GE Research gains access to ORNL supercomputer to optimize jet engines

GE Research announced it has been awarded access to the world’s top supercomputer at the Oak Ridge National Laboratory (ORNL) to support the optimization of jet engines and power generation equipment. With access to the advanced computing capability, GE Research says it will be able to focus on reducing fuel consumption for jet engines as well as on finding new ways to integrate 3D printed parts for improved efficiency and performance.
GE Research was selected to use ORNL’s supercomputer by the Department of Energy (DoE) through its Innovation and Novel Computational Impact on Theory and Experiment (INCITE) program. Now in its 15th year, the program grants access to the supercomputer to external parties for advanced engineering and science projects. Through its award, GE Research is receiving 590,000 node-hours to use ORNL’s Summit Supercomputer.
A team from GE Research’s computational fluid dynamics division will use the Summit Supercomputer to study how complex flow characteristics impact gas turbine performance to improve engine design. The goal is to find pathways for developing more efficient jet engines and power generation equipment. Part of its exploration will also be focused on finding new ways to integrate 3D printed components into engine systems.

“We’re able to conduct experiments at unprecedented levels of speed, depth and specificity that allow us to perceive previously unobservable phenomena in how complex industrial systems operate,” explained Michal Osusky, the project’s leader from GE Research’s Thermosciences group. “Through these studies, we hope to innovate new designs that enable us to propel the state of the art in turbomachinery efficiency and performance.”
This is not the first time that GE has partnered with a National Lab like ORNL. Prior collaborations have led to “significant improvements in combined cycle power plant efficiency, wind energy output and jet engine performance.” Considering this, the company is optimistic its access to ORNL’s Summit Supercomputer will lead to positive results and, crucially, to more sustainable solutions.
GE also leverages in-house supercomputer resources to conduct a number of advanced research initiatives for its Aviation, Power and Renewable Energy businesses. The capability plays an important part in simulating complex fluid dynamics to understand how to design more efficient turbomachinery products.
As part of this project, Osusky and engineers from GE Research and GE Aviation will utilize Large Eddy Simulations (LES) to analyze full 3D engine components to better understand the complex flow physics that influence gas turbine performance. The team will analyze a number of factors, including flow mixing, boundary layer transition, separated flows, multiscale flow structures and coupling between high pressure turbine components.
Notably, GE Additive is also working with ORNL to accelerate the industrialization of additive manufacturing. As part of this ongoing partnership, GE Additive is leveraging the power of the lab’s Summit Supercomputer to rapidly analyze information gathered from metal additive manufacturing systems.
