Madison, WisconsinㅡMarch 20, 2018ㅡThe upcoming WCX18: SAE World Congress Experience will feature more than 30 papers that contain CONVERGE results. These papers span a wide array of topics, including fuel injection, chemical mechanisms, HCCI, GCI, water injection, LES, spray/wall interaction, abnormal combustion, machine learning, soot modeling, and aftertreatment systems. The diversity of topics speaks to CONVERGE's innovative autonomous meshing capabilities, robust physical models, and ability to easily simulate complex moving geometries.
Convergent Science nurtures collaboration with industry, academic, and government entities, and this year's WCX18 papers are a testament to those partnerships. The CONVERGE papers were authored by engineers at organizations such as General Motors, Caterpillar, Ford, Jaguar Land Rover, Isuzu Motors, John Deere, Renault, Aramco Research Center, Argonne National Laboratory, King Abdullah University of Science and Technology (KAUST), Saudi Aramco, and the University of Oxford.
The accompanying bibliography lists the full citation for each paper and the date, time, and location of the accompanying presentation.
