Reply To: particle size distribution in histogram is not continuous

The swirl effect, or (could I call it "larger eddy" if the velocity is decomposed into mean velocity, phase dependent part and stochastic part)?

if this is what you mean, then that's what I tried to find out.

there is no artificial swirl effect in this combustor.

the particle size against time profile shows that particle size does change with time.

the convergence for continuity is 0.01%.

Based on the particle tracks contour, by filtering small particles < 50 micron, there should be no 200 micron particle in my sampling plane location.

the particle number density tracks contour shows the large particle number density diminishing; however, small particle number density should be increasing in the direction of downstream.
