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.
