Reply To: particle size distribution in histogram is not continuous

OK, if it's transient you also need to check the particles reaching the plane have reached an equilibrium. Given burnout etc you may find there's a hold up somewhere so DPM mass is accumulating between the inlet and monitor plane. 

Re the image, as I don't know what you're plotting on I can't really comment. If it's the wall/centre plane you may find particles are central or nearer the wall at different positions down the combustor. If you plot particle tracks do you get a clearer result?
