EAGER: Additively Manufactured Calibration Burner

1742743桑德斯几十年来，研究人员一直使用性能良好的实验室燃烧器来研究高温现象。这些研究使人们能够更好地了解燃烧，这反过来又促进了全世界更有效地使用燃料。传统上，最重要的实验室燃烧器之一是由数百根皮下注射管精心组装而成的，这使得燃烧器表面积远远大于10平方厘米。与此同时，许多研究人员希望燃烧器的表面积达到100平方厘米或更大，以取得新的进展。这个项目通过尝试使用增材制造（也称为3d打印）以一种新的方式制造合适的燃烧器来解决这一难题。利用3d打印技术，人们有望以低廉的价格生产出具有数千个复杂内部通道的燃烧器。在本项目中，这种燃烧器也将在燃烧室中进行测试。如果成功，这种类型的大型负担得起的燃烧器将成为许多研究人员访问。这一发展将具有变革性，允许前所未有的、广泛的进入受控高温环境。最终，它将带来许多好处，比如提高燃油效率、提高可靠性和减少污染。这个项目的大部分将由一名本科生研究员进行，提供出色的研究经验。具体来说，在这个项目中，研究人员将致力于设计、采购和测试一个小型的增材制造燃烧器（AMB），然后是一个大型的AMB。虽然一些燃烧装置最近用增材制造制造，但迄今为止，还没有校准燃烧器以这种方式制造。AMB将使用气相燃料/氧化剂反应物，如甲烷/空气。两个拟议的amb的表面积将分别约为10平方厘米和100平方厘米以上。大面积（100平方厘米或更大）是至关重要的，因为它们提供了更高的信噪比和最小化混淆边缘效应。拟议的大型AMB长度至少为35 cm，因此在本项目之后，它可以用于收集基本的激光视距分子吸收光谱数据，边缘效应偏差不明显。AMB最终将用于光学和物理传感器的校准，基本光谱数据的收集以及气相和固相（烟尘和颗粒）化学的研究。

1742743 SandersFor decades, researchers have used well-behaved laboratory burners to study high-temperature phenomena. These studies have enabled a better understanding of combustion, which in turn has promoted more efficient use of fuel worldwide. One of the most important laboratory burners is traditionally assembled from hundreds of hypodermic tubes in a painstaking manner that discourages burner surface areas much larger than 10 cm-square. Meanwhile, many researchers desire burners with surface areas of 100 cm-square or more to make new advancements. This project addresses this dilemma by attempting to fabricate appropriate burners in a new way, using additive manufacturing (also known as 3-D printing). Using 3-D printing, it is expected that burners with thousands of intricate internal channels can be produced affordably. Such burners will also be tested in a combustion chamber in this project. If successful, large affordable burners of this type will become accessible to many researchers. This development will be transformative by allowing unprecedented and widespread access to controlled high-temperature environments. Ultimately, numerous benefits will be possible, such as improved fuel efficiencies, improved reliability, and reduced pollution. The majority of this project will be carried out by an undergraduate researcher, offering an outstanding research experience.Specifically, in this project, the researchers will aim to design, procure, and test a small additively manufactured burner (AMB), followed by a large AMB. While some combustion devices have recently been fabricated with additive manufacturing, to date, no calibration burners have been fabricated this way. The AMB will operate on gas-phase fuel/oxidizer reactants such as methane/air. The surface areas of the two proposed AMBs will be approximately 10 cm-square and more than 100 cm-square, respectively. Large areas (100 cm-square or more) are critical because they offer increased signal-to-noise ratio and minimize confounding edge effects. The proposed large AMB will be at least 35 cm long, so that following this project, it can be used for collection of fundamental laser line-of-sight molecular absorption spectroscopy data with insignificant edge effect bias. The AMB will ultimately be useful for purposes such as calibration of optical and physical sensors, collection of fundamental spectroscopic data, and studies of gas- and solid-phase (soot and particulate) chemistry.
