satish.iith is on a distinguished road
I tried model a spray injection of ethyl-alcohol-air mixture into a continuous phase of air. geometry- 4.3x4.3x8.6cm. injection point 1mm below the inlet surface. radius of nozzle is 2.15mm.
injection details are like this:
cone, ethyl alcohol as evaporating species and droplet model
point properties - start time=0 and stop time=10000; cone angle = 0; radius=0.00215m

i still can't understand why it asks flowrate given velocity and radius of nozzle??

Discrete Phase model
interaction with cont. phase - on & update DPM source every 10 iterations

In particle treatment, can any one explain what does particle timestep size and number of time steps mean???
Also, can anyone explain where the evaporation of droplet is accounted for???
