A novel hybrid primary break-up model, which is based on coupling of direct numerical simulation (DNS), energy conservation method and linear stability analysis has been implemented into a 3D CFD code and has been tested under conditions typical for Diesel fuel injection in IC engines. Droplet spectra have been pre-calculated for the relevant range of injection and have been stored in a database. From this database actual values in the 3D code are gained during injection time using a quadrilinear interpolation technique to save computational effort. The results are compared with various experiments for non-evaporating and evaporating sprays with promising results.

Abstract
A novel hybrid primary break-up model, which is based on coupling of direct numerical simulation (DNS), energy conservation method and linear stability analysis has been implemented into a 3D CFD code and has been tested under conditions typical for Diesel fuel injection in IC engines. Droplet spectra have been pre-calculated for the relevant range of injection and have been stored in a database. From this database actual values in the 3D code are gained during injection time using a quadrilinear interpolation technique to save computational effort. The results are compared with various experiments for non-evaporating and evaporating sprays with promising results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
