I'm currently working on Sprays with Euler approaches in Ansys CFX17 with water and air both as continuous fluid. I would like to make an investigation about the droplet distribution in my results and want to ask, if there is a possibility or a way to get information about the droplet distribution out of e.g. the volume fraction result? Is there a good option available in the software? Is there a mathematical method available? Does anyone know a correlation?
Thanks in advance!

Since you mentioned both the phases (water and air) were modeled as "Continuous", there is no way to evaluate the droplet distribution. You would have to define one of the phases as "Dispersed" or "Polydispersed", to evaluate the droplet information.
Water droplets in air constitute two different fluids that are mixed at the macroscopic level and not the microscopic level. Hence, you need to use a multiphase model and define two distinct fluids,
Air. Each fluid contains only one component comprising one material (air or water), whose properties can be defined.
Airis the continuous fluid (Continuous Fluid), and
Wateris the dispersed fluid (Dispersed Fluid).
