Vapor/liquid visualization in fuel sprays

摘要: In a series of demonstration experiments, we have shown that exciplex visualization systems can be used to photograph either the liquid or vapor pattern in hollow cone fuel spray. Thus, density information obtained without analysis droplets. Furthermore, through image digitized negatives, quantitative presentations as false color maps and contour plots. The exploit reversible equilibrium which may exist when an excited organic molecule (M * ) reacts with suitable ground state form emitting (E ). emission from M made characteristic E liquid. Because is shifted respect , filters suppress emissions, hence laser sheet excitation, two dimensional sections spray photographed.
