Charging Mechanisms for Electrogasdynamic Spectral Anemometer

摘要

A practical charging mechanism for an electrogasdynamic spectral anemometer using ultraviolet radiation. Ultraviolet radiation issues through windows in the wall of a test section through which flows a turbulent gas. The UV ionizes aerosol particles in the gas flow. A metallic rod which is connected to a high voltage source picks up ions of one polarity and a collector downstream neutralizes the ions of the opposite polarity. The current generated at the collector is measured and analyzed. (Author)
