Reply To: particle size distribution in histogram is not continuous

We actually did some work for potential boundary layer trapping. the boundary layer was intentionally avoided when injecting particles. this work is modeled by RANS model.

I have checked the particle mass balance, comparing the value of particle mass injected from FLUENT and the input value of 34 seconds injection. 8% error was found.  

I also checked the particle parcel number. 3 seconds is flow-through time, you can see Escaped number is 472,633,343, is about 11 times of 45,453,723; and the simulation time is 34 s. roughly speaking, most particles are behaving normally. if there is a small amount of particles stuck in the boundary layer, I suppose it shouldn't be a big deal; is this assumption reasonable to you?

I could generate some animation of particle based one the figure I posted in the previous reply. We can get some overall impression, but not detailed info. Do you think it will be informative?

I will extract some results of particle movement in the near-wall region for LES modeling.

Thank you for your suggestion.
