Title

Hydrocarbon-Vapor Measurements in Pulsed Fuel Sprays

Abstract

A collinear visible and infrared system with a compact sandwich detector design allows for the detection of radiation at both wavelengths simultaneously. With a controlled simulated fuel spray that consists of styrene spheres and methane vapor, vapor concentrations were measured within 10% of the known input value for a large range of particle loadings. Quantitative measurements were also made in a transient isoctane spay with an automotive-type injector. The time-resolved vapor mole fraction, velocity, and mass flux were compared with the transient liquid-phase characteristics obtained with a phase/Doppler anemometer system. -Author
