An illustration of the first computational simulation of a full aircraft GE 90 jet engine, including all major engine components: fan, bypass duct with struts, boost pump and core inlet, high pressure compressor, combustor, high pressure turbine, transition duct with guide vanes, and low pressure turbine. The color contours indicate pressure changes in the engine with the exception of the combustor, which shows temperature changes.

Background: Release date: December 11, 2006 Contact: Andrea Turner, (509) 375-3893 All I want for Christmas is an energy efficient turbine engine RICHLAND, Wash. – Many kids this time of year want their two front teeth, or a radio control turbo blaster toy airplane. Some bigger kids, like adults, want turbine engines that consume less energy and perform more reliably than current models. Pacific Northwest National Laboratory and Advanced Virtual Engine Test Cell, Inc., or AVETeC, in Springfield, Ohio, are embarking on a new adventure to improve computer models that simulate turbine engine performance and, hopefully, reduce the time it takes to manufacture the product. "Today, aircraft engine manufacturers typically build, test, redesign and rebuild prototypes of new engine components, a redundant process that contributes significantly to the $2 billion investment over 7-10 years required to develop a new engine," said Robert Evans Miller, president of AVETeC. "Once a full engine simulation is available, we can dramatically reduce development and maintenance costs, and the time needed to produce an advanced engine." To improve virtual simulations, AVETeC will draw upon expertise at the Department of Energy laboratory in data-intensive computing – computer speak for managing, analyzing and making sense of tons of research data. AVETeC will send its research calculations to a PNNL supercomputer. Because the calculations generate enormous amounts of data, the lab’s researchers will sort and make sense of it by applying new data-intensive software and information technology tools developed by PNNL. “What we’re hoping to accomplish with this partnership of data and expertise is refinement of computer software that can help AVETeC test and improve turbine engine operations virtually, which is cost effective and safer,” said Moe Khaleel director of the Computational Sciences and Mathematics Division at PNNL. “The ‘virtual world’ will allow researchers to design, test and “tweak” the product until an energy efficient and more reliable one is realized, without having to build, rebuild and so on.” “PNNL is recognized worldwide for its science and is looking for applications, and we are an application looking for great science,” said Miller. “This is a naturally symbiotic partnership and will result in a great return on taxpayers’ investment in research.” The Department of Energy's National Nuclear Security Administration's Advanced Simulation and Computing office is funding the work between PNNL and AVETeC through the Data Intensive Computing Environment, or DICE, program. AVETeC created DICE in late 2005 and has since launched 12 projects with multiple partners across the country, including NASA Goddard in Greenbelt, Md., Sandia National Laboratories in Albuquerque, N.M., and Wright-Patterson Air Force Base in Ohio. The program's network will reach the West Coast with the addition of PNNL. The described work is part of PNNL's Data Intensive Computing Initiative. “DICE is a new approach to investigating emerging technology solutions for the high performance computing community. The ultimate goal is to improve the time-to-solution of complex engineering and scientific problems,” continued Miller. The project will cost about $2 million. # # # AVETeC is a not-for-profit public benefit research organization that aims to dramatically reduce the cost and time it takes to design, develop and test new turbine engines for commerce and the military.

PNNL employs 4,300 staff, has an annual budget of more than $750 million, and has been managed by Ohio-based Battelle since the lab’s inception in 1965.
