Abstract
Measurement of gas phase scalar and vector properties within sprays are needed to better understand the vaporization, transport, and combustion of liquid fuels. In the present case, measurement of gas phase vector properties are achieved in the spray field of a twin-fluid atomizer using phase Doppler interferometry. A gas phase scalar, in this case, the concentration of hydrocarbon vapor, is measured using an infrared extinction/scattering technique. When combined, the measurements provide a direct measure of the vaporization characteristics of the spray. The atomizer is operated with methanol under several conditions, including those with and without air-assist. In addition, the spray is studied under reacting as well as non-reacting conditions. The results reveal the insight added by measurement of not only the droplets, but also of the gas phase in the presence of the drops, and identify the need to consider the evolution of the spray in time as well as space.
