[EN] A comparison between the Σ-Y atomization model and a classical DDM approach has been carried out for diesel spray CFD simulations. The Σ-Y model, originally proposed by Vallet and Borghi (1999), is based on an Eulerian ...

Despite great practical interest in how sprays emanate from fuel injectors, the near-nozzle region has remained a challenge for spray modelers. Recently, Eulerian models have shown promise in capturing the fast gas-liquid ...

[EN] An optimization methodology based on a genetic algorithm coupled with the KIVA computational fluid dynamics (CFD) code is applied to the design of a combustion system of a heavy-duty diesel engine fueled with dimethyl ...

This work evaluates the performance of the Σ-Y Eulerian atomization model at reproducing the internal structure of a diesel spray in the near- field. In the study, three different computational domains have been used ...
