In this study cavitating flows in an injection nozzle under time‐depended inlet pressure are calculated using a dispersed bubble dynamics model. The calculations confirm that a transient rise of the nozzle inlet pressure forces cavitation to recede and a sharp decrease of the injection pressure enhances cavitation.
