Spraying a fluid
Hi all,

I would like to model the spraying of a fluid and predict the resulting droplet size distribution. Therefore a correct model for breakup and coalescense of the fluid is mandatory. Did anyone perform such a simulation before? If so could you share some hints and tips?

Kind regards, Pascale

Re: Spraying a fluid
Depends on what you want. I have not yet seen any commercial model that can handle the total atomization from the break up of a film/and or ligaments to large droplets. You would have to guess an initial size distribution. If that is what you need you could look at where the droplet size distribution from a pressure swirl atomizer was investigated numerically and experimentally in a recent M.Sc. student project by Jette Harbo
