ABSTRACT
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 S[sub cr] on particle size in the range of 30 to 90 nm is determined experimentally. The results show that the experimental S[sub cr] 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 S[sub cr] is observed.
