EAGER: Additively Manufactured Calibration Burner

1742743个磨砂器几十年来，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，这反过来又促进了世界范围内更有效地使用燃料。最重要的实验室燃烧器之一传统上是由数百根皮下注射管以一种艰苦的方式组装而成的，这种方式不鼓励燃烧器表面积远远大于10厘米见方。与此同时，许多研究人员希望表面积在100厘米或更大的燃烧器能够取得新的进展。这个项目试图以一种新的方式制造合适的燃烧器，使用加法制造(也称为3D打印)来解决这一困境。使用3D打印，预计可以以负担得起的价格生产具有数千个复杂内部通道的燃烧器。在这个项目中，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为许多研究人员所用。这一发展将是变革性的，因为它允许史无前例的、广泛地进入受控高温环境。最终，许多好处将成为可能，例如提高燃料效率、改善可靠性和减少污染。这个项目的大部分将由一名本科生研究人员进行，提供出色的研究经验。具体地说，在这个项目中，研究人员的目标是设计、采购和测试一个小型附加制造燃烧器(AMB)，然后是一个大型AMB。虽然最近一些燃烧装置是用添加剂制造的，但到目前为止，还没有用这种方法制造校准燃烧器。AMB将对甲烷/空气等气相燃料/氧化剂反应物进行操作。两个拟议的AMBS的表面积将分别约为10厘米见方和100多厘米见方。较大的区域(100厘米或更大)至关重要，因为它们提供更高的信噪比，并最大限度地减少混淆的边缘效果。建议的大型AMB将至少有35厘米长，因此该项目完成后，它可以用于收集基本激光视线分子吸收光谱数据，而边缘效应偏差不明显。AMB最终将用于校准光学和物理传感器、收集基本光谱数据以及研究气相和固相(烟尘和颗粒)化学。

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.
