Spatially and Temporally Resolved Distributions of Liquid in an Effervescent Spray
Original language description
We employed Planar Laser-Induced Fluorescence (LIF) in combination with stereoscopic Particle Image Velocimetry for imaging of concentration and flux fields of liquid phase in an effervescent spray. Light heating oil (LHO) was continuously atomized withaid of pressurised air. The atomizer was operated at atomizing pressures of 0.1 ? 0.5 MPa and Gas?to?Liquid?Ratio by mass (GLR) of 2 ? 50%. Basic spectral and time-resolved LIF characteristics of natural fluorescence of LHO, used for LIF based concentration measurements, are detailed. Instant distributions of concentration and flux were processed into time-average radial profiles and into radial profiles of normalised root?mean?square (rms) fluctuations. Time-average concentration profiles are bell shaped with maximum concentration at the spray centreline and exponential decrease with radial distance. Liquid concentration based half-angles vary with operation conditions between 7.9 and 12.2 deg. GLR causes narrowing of the spray angle w
