Relatively good agreement was found between experiments and simulation for the lower flowrate and segments with multiple bifurcations. Simulated deposition was systematically higher for segments 1 – 12. On the contrary, the first 12 segments agree well for the higher flowrate, however, the deposition in the multiple bifurcation segments was underestimated by the simulation.

Relativně dobrá shoda byla nalezena mezi experimenty a simulací pro nižší průtok a segmenty s více bifurkacemi. Simulovaná depozice byla soustavně vyšší pro segmenty 1 – 12. Naopak, prvních 12 segmentů dobře souhlasí pro vyšší průtok, avšak depozice na segmentech s více bifurkacemi byla podhodnocena simulaci.
