Army Scientist simulates complex diesel injection mist with supercomputer

 The ability to study complex interactions inside a diesel engine gives Army scientists a new perspective that may help design more fuel efficient and effective engines.

Using state-of-the-art supercomputers, Army scientist Dr. Luis Bravo led efforts to create simulations highlighting the first year of his project, allowing them to investigate the jet fuel spray breakup process with microsecond time fidelity and sub-millimeter resolution, while generating petabytes of data.

"The simulation captures the spray primary atomization in the near nozzle dense region using a realistic complex diesel injector," Bravo said. "As diesel sprays are mostly optically thick, the measurements in the dense region are restricted, and the present simulation provides a novel diagnostic method."
