ABSTRACT
Homogeneous nucleation rates of n-propanol in nitrogen are presented. They are obtained from a piston-expansion tube involving the nucleation pulse method which generates a limited number of nuclei that grow into droplets. The detection of the droplets is achieved by a counting method based on a digital charge coupled device camera in combination with a laser light sheet. Nucleation rates between 10[sup 4] and 10[sup 10] cm[sup -3] s[sup -1] are covered for nucleation temperatures between 242 and 273 K. The rates are plotted as isotherms versus supersaturation. Best fit curves are provided for data representation. As in a previous case dealing with n-pentanol nucleation a weak influence of the initial expansion temperature on the nucleation rate is substantiated and explained. Comparison with literature data and classical nucleation theory is provided. © 2002 American Institute of Physics.
