SPECTROPHOTOMETRY TECHNIQUE FOR DROPLET PHASE SPATIAL DISTRIBUTION MEASUREMENTS IN GAS-DROPLET FLOW BEHIND A SUPERSONIC NOZZLE IN A VACUUM
RESUMO
A measurement technique for droplet phase spatial distribution in gas-droplet flows under conditions of rapid evaporation of droplets is proposed. The technique is based on the deposition of droplets colored with a non-sublimated dye on paper substrates and subsequent residue analysis by a spectrophotometry method. The spatial distribution of the droplet phase in the gas-droplet flow, formed under the pulsed outflow of a near-wall liquid film accompanied by the gas flow from a supersonic nozzle into a vacuum, is investigated using the proposed technique.
