ABSTRAKT
Sensitivity of predictions obtained with the atomisation model suggested recently, Vallet et al. (2001), to a choice of a particular turbulence model has been tested. Three different k − ε-type turbulence models, standard, RNG and one including pressure gradient-velocity correlation, have been applied for a test case of air-assisted atomisation. The results show that the pressure gradient-velocity correlation is important and it allows good agreement with experiments for predicted SMD values on the jet axis to be obtained. However, all the models tested underpredict the spray jet spread rate.
