[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 ...

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 ...

[ES] Durante el periodo de docencia del Máster el investigador se ha dedicado al estudio del modelado CFD de chorros Diesel bajo las condiciones de funcionamiento que se dan en los motores Diesel de inyección directa y al ...

El objetivo del trabajo es la realización de cálculos CFD para la simulación de la evolución de un chorro Diesel en condiciones de motor. El alumno empleará un código CFD libre, el OPENFOAM, y será el encargado de configurar ...
