Homogeneous Nucleation Rates for N-Pentanol from Expansion Wave Tube Experiments
Within the scope of joint experiments by the international Nucleation Workshop Group, nucleation experiments on n-pentanol were carried out using a pulse-expansion wave tube. Data were obtained for nucleation at temperatures between 240 K and 360 K. Total pressures of the carrier gas (helium) during nucleation varied from 89 to 109 kPa. The results are presented in tabular form, to facilitate future comparison. Our results are consistent with existing data by Hruby et nl. Comparisons are made to the Kinetic Classical Theory (KCT) as well as to the semiphenomenological theory by Kalikmanov and Van Dongen (KvD-SPT). Although both theories predict nucleation rates that are apparently too low in the temperature range of interest, the KvD-SPT is approximately two orders of magnitude closer to the experimental results.
