Book Flow Independent Fuel Injection for More Consistent Liquid Combustion Using Pintile Injectors

Download or read book Flow Independent Fuel Injection for More Consistent Liquid Combustion Using Pintile Injectors written by Charles Clark and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid jet in crossflow systems are often used as lightweight and efficient mechanisms of atomizing fuel prior to entertainment in the flame holder and combustion, making them integral components of liquid fueled engines. Unfortunately, such systems are susceptible to deviations in both trajectory and breakup rate, depending primarily on the Weber number and momentum flux ratio of the injected jet. In these studies, the effects of solid obstructions, called pintiles, on the variability of liquid jet in cross flow trajectory and breakup are investigated. Initial investigations looked at the impacts of broad geometric parameters on flow independence, using Mie scatter imaging and phase Doppler particle analysis. The results of that investigation yielded an optimal overarching geometry for pintiles. This knowledge was then refined by looking at specific face characteristics of the obstructions, primarily investigating face angle and concavity. Spray characteristics were spatially resolved using LIF/Mie particle sizing techniques, revealing that modest convex surfaces yielded the most consistent breakup characteristics across space, while simultaneously improving the average breakup distance of the liquid jet. Finally, this progression of pintile characteristics is investigated on the effects pintiles have on overarching flame properties, using C2*/CH* chemiluminescence ratios to determine spatially resolved equivalence ratio distributions across a wide range of Weber numbers and momentum flux ratios encompassing breakup regimes from the enhanced capillary modes through to shear breakup modes. Results from these studies demonstrate significant improvement of combustion properties from the introduction of the pintiles.

Book An Experimental Investigation of Fuel Spray Vapor Phase Characterization

This book was released on 1989 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study of an infrared laser extinction technique for measuring fuel vapor flux in evaporating liquid fuel sprays was conducted. The infrared laser extinction technique consists of three separate measurements: a visible light angular scattering measurement, a visible light line-of-sight extinction measurement and an infrared line-of-sight extinction measurement. Using this technique, vapor flux along with other spray parameters such as mean drop size and size distribution were measured for a pressure atomized, isooctane fuel spray. Line-of-sight infrared extinction measurements were deconvoluted to obtain radial variations of vapor concentration. Peak vapor concentrations were measured at the spray center due to air entrainment effects. Based on the radial mass fraction and measured gas phase velocity profiles, the fuel vapor mass flux was calculated; most of the vapor flux was contained in the center of the spray at all axial locations. The fuel vapor mass flux was integrated over the spray area at each axial location to obtain fuel vapor mass flow rates. Comparisons were made between the infrared laser extinction technique and a Phase/Doppler Particle Analyzer (P/DPA) in terms of several spray parameters including drop size, size distribution and, in particular, vapor flux. Size comparisons were conducted on a spatially resolved and line-of-sight basis. While the spatially resolved comparisons indicated similar trends, the angular scattering measurements consistently predicted Sauter mean diameter results $sim$10 $mu$m larger than those obtained from the P/DPA. Comparisons of measured total fuel vapor flow yielded differences of 7 to 40% between the P/DPA and infrared extinction technique. A detailed error analysis was performed to determine the error sensitivities of the vapor concentration to the measured parameters as a function of spray radius. The vapor concentration was relatively insensitive to the measured drop size distribution due to the fact that the vapor absorption was the most dominant mode of extinction. The vapor concentration was most sensitive to the measurement of the infrared extinction ratio. An upper limit for the overall error in the vapor concentration measurement was estimated at 15% over the spray radius.
