Hello there,
I am working on a diesel spray simulation in new engine design. I do not have any experimental data for the diameter of the droplets of the spray. Can anybody suggest me a proper method to determine the droplet diameter for an initial case. The operating condition and the other point properties for the DPM is as below.

2D Problem with group injection.
Number of stream= 20
velocity of the spray= 150m/s
Nozzle exit diameter is approx 1.3mm

Waiting for a helpful reply. Thank you so much in advance.
