| Popis: | In the present study, we experimentally investigated the aerosol-particle sustaining features of a porous-walled rubber foam tube model according to outlet humidity and temperature variations. An oleic acid aerosol is used as the inlet working fluid and the embedded particle diameters are in the range of 6–10 μm. To analyze particle size distribution, a wide-ranging particle spectrometer is employed, and particle sizes are measured at the inlet and outlet of the tube. Variance analysis is performed to evaluate the significance level of various tube-wall conditions, including dry and moist aerosol conditions at room and body temperatures. For the cases of larger particle sizes, the sustaining rates are increased when the porous wall condition is moist and at body temperature. |
