Hydrocarbon Vapor Measurements in Fuel Sprays: A Simplification of the Infrared Extinction Technique
An equal optical thickness approximation that greatly simplifies the application and data reduction of the infrared extinction technique for measuring fuel vapor concentrations in sprays is investigated. A general approach is given, with specific results for a 3.39- and a 0.6328-μm-wavelength system. It is shown that the infrared (3.39-μm) drop optical thickness can be approximated by the use of the visible (0.6328-μm) optical thickness for drop size distributions with area mean diameters greater than 20 μm for hydrocarbon fuel sprays. -Author
