AB - Loss of the number of nanoparticles within pipe may lead to significant  change of particle number distribution, total mass concentration and  particles mean size. The experiments of multiple dispersion aerosol particles  ranging from 5.6 nm to 560 nm in straight pipe are carried out using a fast  mobility particle sizer. The particle size number distribution, total number  concentrations, geometric mean size and volume are acquired under different  pipe lengths and Reynolds numbers. The results show lengthening the pipe and  strengthening the turbulence can promote the particle deposition process. The  penetration efficiency of smaller particle is lower than the larger one, so  the particle mean size increases in the process of deposition.
