Performance of elliptical nozzles on the spray dynamics of convergent and constant section nozzles by means of a Sigma-Y coupled model

[EN] In this paper, a computational study on the differences between a convergent and a constant section elliptical nozzle is performed. Coupled internal-external flow simulations were carried out by means of a sigma -Y model experimentally validated. The differences reported in terms of internal fl...
