Dispersed Two-Phase Flow Modelling for Nuclear Safety in the NEPTUNE_CFD Code

Table 4

Daughter droplets diameters of two parents droplets after a binary collision for different regimes.

Collision outcome	Small droplet diameter	Large droplet diameter	Final droplet diameter	Final direction velocity	Observations
Bouncing			and	and	No change
Coalescence					Creation of one droplet
Stretching separation			and	and	Satellite droplets are neglected
Reflexive separation					3 droplets are created
Splashing					20 droplets are created
