The Effect of Vertical Turbulent Fluctuations in the Atmosphere on the Collection of Aerosol Particles by Cloud Drops
Publisher: American Meteorological Society
Abstract: A one-dimensional model of the effect of the vertical component of atmospheric turbulent fluctuations on the collection of micron-size aerosol particles by cloud drops is presented. The model includes simultaneous effects ...
Numerical Collision Efficiencies for Small Raindrops Colliding with Micron Size Particles
Publisher: American Meteorological Society
Abstract: Numerical calculations were carried out to determine collision efficiencies for small raindrops with micron size particles based on a numerical description of the axisymmetric steady-state flow about a rigid sphere for ...
A Numerical Determination of the Efficiency with which Electrically Charged Cloud Drops and Small Raindrops Collide with Electrically Charged Spherical Particles of Various Densities
Publisher: American Meteorological Society
Abstract: Numerical computations were carried out to determine the efficiency with which electrically charged cloud drops and small raindrops of diameters ranging from 84 to 866 µm collide with electrically charged particles of ...
A Numerical Determination of the Efficiency with Which Spherical Aerosol Particles Collide with Spherical Water Drops Due to Inertial Impaction and Phoretic and Electrical Forces

Abstract: A theoretical model to compute the efficiency with which aerosol particles of radius 0.5≤r≤10 ?m collide with water drops of radius a=42, 72, 106, 173, 309 and 438 ?m falling at terminal velocity in air is presented. ...
On the Effect of Electric Charges on the Scavenging of Aerosol Particles by Clouds and Small Raindrops
Publisher: American Meteorological Society
Abstract: A theoretical model is described which determines the efficiency E with which aerosol particles of radius r are collected by water drops of radius a due to the combined action of Brownian diffusion, thermo- and diffusiophoresis ...
A Numerical Investigation of the Effect of Electric Charges and Vertical External Electric Fields on the Collision Efficiency of Cloud Drops
Publisher: American Meteorological Society
Abstract: The aerodynamic interaction between electrically charged cloud drops in the presence of vertical external electric fields was numerically investigated for 800 mb and +10°C. The collector drops had radii between 11.4 and ...
A Numerical Investigation of the Effect of Electric Charges and Vertical External Electric Fields an the Collision Efficiency of Cloud Drops: Part II
Publisher: American Meteorological Society
Abstract: The numerical model of Schlamp et al. (1976) for determining the collision efficiency of electrically charged or unchanged cloud drops in the presence or absence of a vertical electric field has been extended to study the ...
