    Nucleation and growth rates of homogeneously condensing water vapor in argon from shock tube experiments (1993)
    Springer
    Mineralium deposita 28 (1993), S. 521-530 
    Details
    ISSN: 1432-1866

    Topics: Geosciences
    Notes: Abstract A special shock tube process combining a reflected expansion wave with a weak shock wave is analyzed and calibrated. The process is employed to transfer water vapor carried in argon into a known supersaturated state for a short period of time (0.5 ms). During that period steady state homogeneous nucleation takes place followed by condensational growth. Nucleation and growth rates are measured by a 90° Mie-light scattering technique in the temperature range 200–260 K. The results are compared with existing theoretical models.

    Schlieren interferometry applied to a gravity wave in a density-stratified liquid (1985)
    Springer
    Experiments in fluids 3 (1985), S. 261-269

    Notes: Abstract A stably density-stratified liquid is produced in a rectangular glass tank by variation of the concentration of salt in water as a function of height. The glass tank is placed into the parallel beam of a schlieren interferometer with Wollaston prism adjusted to produce straight vertical fringes. A gravity wave of the cross wave type is excited and the resulting periodically deforming fringes are recorded by taking photographs. A method is developed to obtain from the fringe patterns results about propagation of the wave in space and time and about amplitude attenuation. The results are compared with the linear theory of Thomas and Stevenson (1972) and excellent agreement is found within the limits of the linear approach.

    Design and performance of a rapid piston expansion tube for the investigation of droplet condensation (1998)
    Springer
    Experiments in fluids 24 (1998), S. 300-307

    ISSN: 1432-1114

    Notes: Abstract  A piston expansion tube (pex-tube) is described which has been developed for the investigation of homogeneous nucleation in a supersaturated vapor and subsequent droplet growth. The design of the tube with periphery is discussed as well as the underlying gasdynamics. Examples for the measurement of nucleation and growth rates in a binary mixture of n-propanol/water carried in nitrogen demonstrate performance and range. The focus of the paper is on the determination of the nucleation state. It is shown that this state may not be based on an adiabatic expansion when helium is used as carrier gas instead of argon or nitrogen.

    Experimental results on the rate of nucleation in supersaturated n-propanol, ethanol, and methanol vapors (1989)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The homogeneous nucleation of three supersaturated alcohol vapors carried in argon is investigated experimentally. A gasdynamic shock tube method serves to subject the vapors to short supersaturation pulses. The growing nuclei are detected in number and size by Mie-light scattering. The results provide the supersaturation over a wide range of temperature for the nucleation rate of 108 cm−3 s−1. Comparison with the classical nucleation theory (CNT) exhibits increasing divergence with decreasing temperature.

    Homogeneous nucleation rates of n-pentanol in nitrogen measured in a piston-expansion tube (2000)

    Notes: Homogeneous nucleation rates of n-pentanol in nitrogen are presented. They are obtained from a piston-expansion tube (pex-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 new counting method developed on the basis of a CCD camera in combination with a laser light sheet. Nucleation rates between 104 and 109 cm−3 s−1 are covered for three nucleation temperatures 250, 260, and 270 K. The rates are plotted as isotherms vs supersaturation. Influence of the initial expansion temperature and the nucleation pressure on the nucleation rate is identified. Comparison with results available in literature and classical nucleation theory (CNT) is provided. © 2000 American Institute of Physics.

    Notes: 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 104 and 1010 cm−3 s−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.

    Binary nucleation at low temperatures (1985)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 83 (1985), S. 6425-6431

    Notes: The onset of homogeneous condensation of binary vapors in the supersaturated state is studied by means of the unsteady expansion in a shock tube. The experiments are concerned with low temperatures down to 220 K which are of particular interest for atmospheric conditions. Two representative systems, ethanol/n-propanol and water/ethanol, are investigated since they allow a sufficient theoretical description. The first system forms a nearly ideal solution, whereas the latter one is an example of a strongly nonideal mixture. For either system vapor mixtures of various compositions are diluted in dry air at small mole fractions and expanded in the driver section from room temperature. The onset of homogeneous condensation is detected optically and the corresponding thermodynamic state is evaluated. The experimental results are compared with the binary nucleation theory and the particular problems of the theoretical evaluation at the low temperatures are discussed. The use of surface tension values derived for small binary droplets1 in the nucleation theory is mandatory to restore agreement between theory and experiment for the surface active system water/ethanol.

    Notes: [Auszug] The method used for drying is to cook the fresh ripe fruit in the ashes of a fire for an hour. The cooked product is left for a day and then it is peeled, the seeds removed, and it is cut into small pieces which are arranged on a net to a depth of four or five inches. This net is suspended over a ...
