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...

| Resumo: | [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 flow and spray parameters present the cavitation as an important effect in the elliptical nozzle geometries. The conclusions suggest a mixture improvement potential for the cavitating elliptical nozzles. |
