Abstract: Laboratory experimentation was undertaken to investigate the effects of various soluble and insoluble nuclei on the freezing temperature of water droplets. The freezing temperature and size of over 15,000 droplets were ...

Abstract: This paper shows the necessity of determining experimentally the collection efficiency of an aerodynamic probe, before using it to collect an aerosol. The experimental techniques described herein, although applied to a ...

Abstract: A system is described for accurately generating droplets of known size in the diameter range 300?500 ?, and measuring their terminal velocity in air. The error in terminal velocity is <0.5%. Measurements were made using ...

Abstract: A vertical wind tunnel which will support droplets in the size range of 50?200 ? is described. It consists of three sections, a diffuser, a profile forming section, and the observational section. The construction details ...

Abstract: The results of an experiment determining the collection efficiency of a cylinder at aircraft speeds are presented and compared with the theoretical computations of Langmuir and Blodgett. It was found that the agreement was ...

Abstract: As a means of studying ice nucleation, snow and ice pellets collected from the tops of clouds were melted and refrozen in order to determine their freezing temperatures. In all cases where a definite cloud top temperature ...

Abstract: Measurements of evaporation rates suggest that when water droplets are exposed to certain contaminants, a monolayer can form which inhibits evaporation. Experimental droplet evaporation rates are compared to theoretical ...
