Furthermore, models of fast power and exponential decay trend are demonstrated to uncover the relationship among enhancement factor of deposition velocity behind bend, dimensionless distance behind bends and particle Stokes number. Where N d and N f are the particle number deposited in a bend and those in the straight duct of fully developed flow section with a length D, respectively. Particle deposition distribution and deposition velocity in 90 ventilation bends with different surface materials were analyzed numerically, and the simulation results were also validated with experimental data.	./cache/cord-304048-wncau6zm.txt	./txt/cord-304048-wncau6zm.txt
