I am simulating a spray using pressure swirl atomizer in Fluent.
It is a transient case.
I am interested in variation of Suater mean Diameter (SMD) of droplets over the time.
I cam calulate overall SMD and SMD at last step through DPM reports. However can anyone suggest if there is any way to get a plot/report of SMD with time?
My suggestion is that, try to save or write down overall SMD at a fixed interval of time and then plot the graph with it.
@Rashed
Yeah that looks obvious solution. But how to save it after every timestep? I mean its not a property like temperature or pressure where we can save volume or mass averaged values after every time step.
Just run it for 100 or 1000 time step and write down the time and overall smd from DP summary. Again, run it for a fixed interval and write down the smd and time. The overall smd will change with the timestep as the more particle will join in the chamber. Check the attached image. I run the calculation at 3ms time interval. You should write down the time and overall smd after a certain time interval and plot the graph.
