  • Understanding air core formation in hydrocyclones by

    28032008  The air core occurs because of the low pressure region in the hydrocyclone drops below atmospheric pressure, which allows air to enter into the cyclone (Nowakowski et al, 2004) The actual formation of the air core is not known, however the prevalent thought is that the air enters from both outlets and eventually reaches a critical point, which combines the two air vortices ( Cullivan et al
