About calculating droplet diameter for atomization
 
Hi All,

I'm simulating the breakup of droplet inside a cylindrical nozzle. For this purpose I wanted to calculated the frequency of the droplet diameter distribution.

For calculating this the domain is divided in to 'n' number of sections with each section having a fixed width. Each section is analysed for the droplet which is assumed to be spherical. Now each droplet diameter is calculated from droplet volume obtained by taking into account the volume fraction occupying the computational meshes and also taking the mesh size into account. To move forward with this method I wanted to know the location of a particular cell. Is there any tool by which I can know the centroid of the cell and the volume fraction present in it.

Thanks,

Kshitij
