In discrete droplet model, generally how many droplets 1 parcel should represent ? I am trying to solve with my code gasoline vaporising spray and need this input. Thanking you.

Hi,

You have got a size cathegories from the spray distribution. For each size class you have a parcel. You should get the number of droplets to get the same mass flow rate for the whole modelled spray as it is in real spray. It is typically easy to write a small program to generate the input data from the measurements.

So I do remember to have a spray definition with 6 size classes, each size with 10 parcels each parcel with tens to thousands of droplets in. (it was quite poor description of spray on an old SGI (.

hope this helps
