摘要: The cloud water collectors have been developed for use at normal and severe atmospheric conditions, high wind speeds subzero temperatures. Aspiration efficiencies can be considerably improved by using baffled sampling heads, which reduce the speed in vicinity of aspiration nozzle. It was found that a semi-empirical formula reported Vincent et al. [ I ] probably used describing properties these heads. A numerical model particle trajectories shall facilitate more detailed analysis
