SGER: Volatility Correlations in Blended Hydrocarbon Fuels

摘要提案编号：csts -0535791首席研究员：Ashford， marcus隶属机构：阿拉巴马大学提案标题：SGER：混合碳氢燃料中的挥发性相关性该提案是作为一份主动提交给化学和运输系统部门的探索性研究小额拨款（SGER）类别的提案，随后由热系统计划的热传输和热处理子元素资助。该项目的目标是建立类似汽油的燃料的沸腾特性（与表面接触）与该燃料的挥发性之间的相关性。挥发性描述了在给定温度和压力下燃料会蒸发多少。这项研究对环境的影响是相当大的：碳氢化合物燃料是全球主要的能源来源。仅交通运输部门就产生了全国挥发性有机化合物（VOC）、碳氢化合物（包括致癌物、急性毒素和烟雾形成的前体）排放量的近一半。汽车和轻型卡车几乎完全依靠燃烧发动机的动力装置，这些装置消耗液态碳氢化合物混合燃料，而这种燃料在燃烧前必须蒸发。由于燃料汽化预测不正确而导致的加油不精确是造成汽车发动机几乎所有尾气排放VOC的原因。这项研究将使人们更深入地了解燃料的蒸发特性，促进精确加油和显著减少排放。

ABSTRACTProposal Number: CTS-0535791Principal Investigator: Ashford, MarcusAffiliation: University of AlabamaProposal Title: SGER: Volatility Correlations in Blended Hydrocarbon FuelsThe proposal was received as an unsolicited submission to the Chemical and Transport Systems Division in the Small Grants for Exploratory Research (SGER) category and was subsequently funded by the Thermal Transport and Thermal Processing Sub-element of the Thermal Systems Program. The goal of project is to establish correlations between the boiling characteristics (in contact with a surface) of a gasoline-like fuel and that fuel's volatility. Volatility describes how much of a fuel will vaporize at a given temperature and pressure. The environmental implications of this research are considerable: hydrocarbon fuels are a major global energy source. The transportation sector alone produces almost half of nationwide emissions of volatile organic compounds (VOC), hydrocarbons that include carcinogens, acute toxins and precursors to smog formation. Automobiles and light trucks depend almost exclusively on combustion engine powerplants that consume liquid hydrocarbon blended fuels, which must be vaporized prior to combustion. Fueling imprecision caused by improper prediction of fuel vaporization is responsible for virtually all tailpipe VOC emissions from automobile engines. This research will lead to more intimate knowledge of the fuel's vaporization characteristics, facilitating precise fueling and significant emissions reductions.
