Condensation of supersaturated n-butanol vapor on monodisperse submicrometer D-Mannose and L-Rhamnose particles is investigated in a flow cloud chamber (FCC). The dependence of the critical supersaturation Scr on particle size in the range of 30 to 90 nm is determined experimentally. The results show that the experimental Scr decreases with increasing particle size, qualitatively in agreement with that predicted by Kohler theory, but quantitatively, smaller than the theoretical prediction. The condensation of supersaturated vapor on singly-positively-charged particles with diameters of 30, 60, and 90 nm is examined. A slight effect of charge on Scr is observed. |
