Abstract: The wave-induced movement of oil lenses and other floats was studied by using mechanically generated gravity waves in a water tank. The measured surface drift velocities were in all cases higher than those predicted by the ...

Abstract: The performance of the Twomey-type cloud condensation nucleus (CCN) counter is evaluated by a numerical simulation and found to be better than that predicted in an earlier study. Due to a lack of data on CCN spectra at low ...

Abstract: A vertical plate, steady-flow, thermal diffusion chamber designed for use as a cloud condensation nucleus counter is described. In this instrument, phoretic forces are shown to limit the maximum available growth time to a ...

Abstract: Condensation of water vapor an various surfaces was studied experimentally. For surfaces with an airwater contact angle ? less than 20° the experimentally determined values of critical supersaturation Sc. agreed with those ...

Abstract: The performance of the conventional horizontal plate thermal diffusion chamber as a cloud nucleus counter was studied. Numerical calculations were performed in order to follow the simultaneous drop growth and sedimentation ...

Abstract: Growth rate measurements were made for water drops grown on nuclei in atmospheric air samples taken in Rolla, Missouri. Rolla, having a population of 15,000 and very little industry, is relatively free of urban pollutants. ...

Abstract: Analytical expressions are derived for temperature and vapor pressure profiles in a vertical-plate, steady-flow, thermal diffusion chamber designed to count cloud condensation nuclei. The influence of longitudinal diffusion ...

Abstract: A systematic series of condensation coefficient measurements of water have been made using the University of Missouri?Rolla cooled-wall expansion chamber which simulates the thermodynamics of cloud. This coefficient is ...

Abstract: Nucleation experiments with monodisperse NaCl aerosols showed good agreement with the Köhler theory relating the critical super-saturation Sc to the dry size. Aerosols produced by condensing NaCl showed the same Sc as those ...
