Highlights • A numerical model is presented for acoustic cavitation in water with non-condensable bubble nuclei.• The phase change has a significant effect on bubble growth and collapse dynamics during acoustic cavitation.• As the bubble nucleus size increases and the acoustic frequency increases, the cavitation threshold increases beyond the Blake threshold.• The threshold predictions fitted as a function of bubble nucleus size and acoustic frequency can be applied to acoustic cavitation in water with a wide range of threshold data in the previous works.
