Abstract The predictive capability of two different numerical cavitation models accounting for the onset and development of cavitation inside real-sized diesel nozzle holes is assessed on the basis of the referenced experimental data. The calculations performed indicate that for the same model assumptions, numerical implementation, discretization scheme, and turbulence grid resolution model, the predictions for differently applied physical cavitation sub-models are phenomenologically distinct from each other. We present a comparison by applying a new criterion for the quantitative comparison between the results obtained from both cavitation models.
