KIVA-4

Kiva-4

The KIVA family of Computational Fluid Dynamics (CFD) software predicts complex fuel and air flows as well as ignition, combustion, and pollutant-formation processes in engines. The KIVA models have been used to understand combustion chemistry processes, such as auto-ignition of fuels, and to optimize diesel engines for high efficiency and low emissions. Using Los Alamos National Laboratory’s KIVA code, Cummins reduced development time and cost by 10%–15% in developing its high-efficiency 2007 ISB 6.7-L diesel engine that was able to meet 2010 emission standards in 2007. At the same time, the company realized a more robust design and improved fuel economy while meeting all environmental and customer constraints.

A commercial license is required for any use beyond personal, informal use. Please contact Mariann Johnston via email at: mjohnston@lanl.gov, or by telephone at: 505-667-4391, for additional information on KIVA.
