Computing – Supercharging injector design …


An allocation of 15 million hours on Oak Ridge National Laboratory’s Titan supercomputer could accelerate advances in fuel injector design, enabling automakers to meet government fuel economy regulations, say researchers at General Motors and ORNL. “The current design optimization process is very time- and labor-intensive,” said Sreekanth Pannala of ORNL’s Computer Science and Mathematics Division. “As a result, it is not possible to fully investigate the numerous geometry and operating parameters and truly optimize the injector design for best fuel efficiency.” By employing Titan, however, researchers can simulate a large matrix of injector designs over a wide range of operating conditions, analyze the results and validate against experimental measurements. This approach can reduce the development time from months to weeks. The award was made through the Department of Energy’s Advanced Scientific Computing Research Leadership Computing Challenge.
