Abstract

This paper develops understanding and appropriate techniques for characterising mist generation from super-saturated liquid-air systems. Whilst the technology for this technique originates from Wilson (1897), to date mainly a qualitative understanding of the relationship between mist characteristics and initial control conditions exists. Here, an improved design of cloud chamber, which facilitates accurate control, is described, and temporal measurement techniques for thermodynamic control parameters are proposed and appraised. Mist characteristics are quantified using transient laserdiffraction measurements. Expansion is described by a polytropic thermodynamic process with appropriate coefficients, and the influence on mist generation of primary control parameters expansion rate, expansion ratio and initial temperature are quantified and analysed. Applications include fundamental studies of two-phase combustion, quenching explosions by ultra-fine water mists and well as the traditional meteorological interest.
