Hello

I am working on droplet injection into a pipe.
In the Fluent theory manual, the droplet-wall interaction is exposed (am attaching a picture for quick reminder of the interaction in Fluent).

Above the boiling point, the droplets might rebound or splash. The splashing is described in details. It seems that the same behavior is described both for interaction happening below or above the boiling point, with droplet deposition occuring (from 0 to 30% of the impacting mass)

However, I was thinking that above the boiling point, or more precisely above the Leidenfrost temperature, no deposition could happen.

I thus wanted to know if someone could confirm the existence of deposition, or if actually the splashing above the boiling point is defined with no deposition in Fluent. (I know that in StarCCM there are no splashing deposition above the boiling temperature)
