EXPERIMENTAL STUDY ON NANOPARTICLE DEPOSITION IN STRAIGHT PIPE FLOW
Abstract
Loss of the number of nanoparticles within pipe may lead to significant change of
article number distribution, total mass concentration and particles mean size. The
xperiments of multiple dispersion aerosol particles ranging from 5.6 nm to 560 nm
n straight pipe are carried out using a fast mobility particle sizer. The particle size
umber distribution, total number concentrations, geometric mean size and volume
re acquired under different pipe lengths and Reynolds numbers. The results show
engthening the pipe and strengthening the turbulence can promote the particle deposition
rocess. The penetration efficiency of smaller particle is lower than the
arger one, so the particle mean size increases in the process of deposition.
