This project concerns a study of the combustion performance of an emerging bio-derived liquid fuel, isobutanol, and its mixtures with gasoline in an environment that promotes spherical flames during droplet combustion. The relevance of this work stems from the fact that combustion engines such as gasoline engines are powered by petroleum-based fuels, and the supplies of these fuels are limited. Therefore, the continuous consumption of these non-renewable liquid fuels and concerns over the harmful emissions have highlighted the need for renewable biofuels with sustainable production and reduced emissions. In this context, this work aims to provide a fundamental understanding of the combustion dynamics of biobutanol and its blends with practical transportation fuels to determine their potential performance in combustion engines. These efforts will significantly benefit society by guiding the development of improved fuel efficiency and providing insights into reducing harmful emissions, and thus offering solutions to climate change. Broader impacts from an educational perspective for this project include providing underrepresented minority students at both undergraduate and graduate levels with opportunities to conduct independent research, discover new knowledge, and explore practical applications. Furthermore, this work will offer various K-12 outreach opportunities. These programs will engage more minority students, attract them to pursue a career in science and engineering, and thus build a more diverse workforce in Science, Technology, Engineering, and Mathematics (STEM).The goal of this research is to deepen the fundamental understanding of the combustion processes of bio-derived liquid fuels as promising additives or alternatives for petroleum-based fuels. The specific objectives of this project are to (1) establish a cost-effective Multiphase Droplet Burning Facility at Prairie View A&M University to build the institutional research capacity as a Historically Black College and University in the areas of droplet combustion and thermo-fluids; (2) build an experimental platform to quantitatively extract Soot Volume Fraction during the combustion of isobutanol and its mixtures with petroleum-based fuels; and (3) develop an experimental database for the combustion of isobutanol to evaluate its potential for being a desirable additive for gasoline to reduce the consumption of petroleum-based liquid fuels as well as harmful emissions during combustion. Results obtained will advance the understanding of how bio-derived fuels combust in the context of petroleum-based liquid fuels. Experimental combustion data collected will also be a valuable database for the research community for developing, validating, and optimizing numerical models.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目研究了一种新兴的生物衍生液体燃料异丁醇及其与汽油的混合物在液滴燃烧过程中促进球形火焰的环境中的燃烧性能。这项工作的相关性源于这样一个事实，即汽油发动机等内燃机是以石油为基础的燃料，而这些燃料的供应是有限的。因此，这些不可再生液体燃料的持续消费和对有害排放的担忧突出了对可持续生产和减少排放的可再生生物燃料的需求。在此背景下，本工作旨在提供对生物丁醇及其与实际运输燃料的混合物的燃烧动力学的基本了解，以确定其在内燃机上的潜在性能。这些努力将引导提高燃油效率的发展，并为减少有害排放提供见解，从而为气候变化提供解决方案，从而显著造福社会。从教育角度来看，该项目的更广泛影响包括为本科生和研究生中人数不足的少数族裔学生提供进行独立研究、发现新知识和探索实际应用的机会。此外，这项工作将提供各种K-12外展机会。这些项目将吸引更多的少数族裔学生，吸引他们从事科学和工程方面的职业，从而建立一支更加多样化的科学、技术、工程和数学(STEM)劳动力队伍。这项研究的目标是加深对生物衍生液体燃料作为石油燃料的有前途的添加剂或替代品的燃烧过程的基本理解。这个项目的具体目标是：(1)在普雷里维尤农工大学建立一个成本效益高的多相液滴燃烧设施，以建设作为一个历史悠久的黑人学院和大学在液滴燃烧和热流体领域的机构研究能力；(2)建立一个实验平台，定量提取异丁醇及其与石油燃料混合物燃烧过程中的碳烟体积分数；(3)开发一个关于异丁醇燃烧的实验数据库，以评估其作为汽油添加剂的潜力，以减少石油液体燃料的消耗和燃烧过程中的有害排放。所获得的结果将促进对生物衍生燃料在以石油为基础的液体燃料的背景下如何燃烧的理解。收集的实验燃烧数据也将是研究社区开发、验证和优化数值模型的宝贵数据库。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
