Sorry for replying late due to the maintenance of this forum.

there is a bluff body in this combustor. I believe the effect range will be confined to the upstream section.

I extracted the particle number data in one figure.

in the very beginning, x = 1 mm, the particle size distribution does not look like the Rosin-Rammler distribution.

in the very end x =1.95 m, the particle size is uniformly distributed under 70 microns.

you can also see there is no particles with 40 micron. 

the total number of particle (parcel) also changes.

I sampling this for certain time, the dpm file reaches up to 400 Mb. I am not sure where sampling time is enough.Â
