High-performance computing accelerates advanced engine development


Oak Ridge National Laboratory’s (ORNL’s) Dean Edwards and a crosscutting team leveraging expertise in computational science and engine and emissions-control technologies are working with Ford Motor Company to develop and demonstrate a method for identifying the impact of engine parameters that promote combustion instability in spark-ignition engines.

Using ORNL’s Titan supercomputer, researchers are conducting a second cycle of computational simulations to refine the sophisticated model generated using open geometry.

“In the past researchers had to rely on highly simplified engine models to simulate the thousands of consecutive engine cycles needed to study the cycle-to-cycle variability with statistical accuracy,” Edwards said. Now access to Titan’s capabilities allows researchers to develop highly detailed models in far less time. The resulting method will soon be available to industry.

ORNL will continue its work with industry partners Ford and Convergent Science to accelerate development of advanced internal combustion engines that will enable Ford and other automotive manufacturers to meet increasingly stringent fuel-economy and emissions standards.
