Diagnostics of water in multiphase flow systems
Abstract
Laser-induced Raman scattering is resorted to for instantaneous and local measurements of droplet density. The approach is seen as combining the advantages of the extinction method (passing a beam of light through the droplet medium) and collection techniques (involving immersion of a mechanical probe into the stream) capable of yielding pointwise measurements. Distinct Raman shifts associated with phases of the same species of molecules or particles provides information on phases present, as well as on distinct substances. A droplet generator used in the experiments is described. The technique is useful for studying governing mechanisms in combustion research, injection cooling, and pollution control where the behavior of liquid droplets in air is of interest.
