Hello everyone!! I am doing a simulation of coughing and sneezing using sprayFoam solver of OpenFOAM 6. I want to implement collision, coalescence and breakup models for my simulation. I have searched these models and I have found that there are two collision-coalescence models (O'Rourke and trajectory) and six breakup models (TAB, ETAB, Reitz-Diwakar, Reitz-KHRT, Pilch-Erdman and SHF).
Which of the breakup models is the best? Which breakup model should I use for my case, can any one suggest?
Also which collision-coalescence model should I use?

Have a go in the theory section of the User Guide. Sometimes SIEMENS gives some pointers for the application range of the models.
