Engineering Research Equipment: Laser Diagnostics for Microscale and Microwave Enhanced Combustion

该奖项支持在普林斯顿大学机械与航空航天工程系（MAE）安装基于激光的燃烧诊断系统，包括Nd：YAG脉冲激光器、Nd：YAG泵浦染料激光器、光谱仪和图像增强相机。该设备将用于支持微尺度燃烧、微波增强燃烧、非平衡等离子体辅助燃烧和高压燃烧的基础研究，并增加教育课程。首先，该设备支持研究由于壁火焰相互作用和非连续质量传输，微波增强燃烧中的微波火焰相互作用，非平衡等离子体放电火焰中的电子碰撞解离以及高压下的火焰动力学而调查微尺度燃烧中的独特现象。开发的设备和新的诊断方法将被纳入研究生和本科生的实验室课程，以加强学生的培训。 通过使用该设备开发的过滤瑞利散射和双线LIF将向本科生和研究生实验室课程进行演示，以使学生熟悉燃烧诊断的最新能力。 本科生在研究实验室的参与将为学生提供一个独特的机会。这些设备还将被纳入特伦顿高中少数民族高中生的夏季“动手科学”项目。此外，该设备将用于与普林斯顿能源中心的校内合作以及与德雷克塞尔大学等离子体研究中心的校际合作。

ABSTRACTThis award supports the installation of a laser-based combustion diagnostic system including a Nd:YAG pulsed laser, a Nd:YAG-pumped dye laser, a spectrometer, and an image intensified camera in the Department of Mechanical and Aerospace Engineering (MAE) at Princeton University. This equipment will be used to support fundamental research on microscale combustion, microwave-enhanced combustion, non-equilibrium plasma-assisted combustion, and high-pressure combustion, and to augment the educational curriculum. Primarily, the equipment supports research to investigate unique phenomena in microscale combustion due to wall-flame interactions and non-continuum mass transport, microwave-flame interactions in microwave- enhanced combustion, and electron-impact dissociation in non-equilibrium plasma-discharged flames, as well as flame dynamics at high pressures. The equipment and the new diagnostic approaches developed will be integrated into both the graduate and undergraduate laboratory courses to enhance student training. Filtered Rayleigh scattering and two-line LIF, developed by use of this equipment, will be demonstrated to both undergraduate and graduate laboratory classes to familiarize students with the state of the art capabilities in combustion diagnostics. The participation of the undergraduates in the research laboratories will provide a unique opportunity for the students. The equipment will also be integrated into the summer "hands-on science" program for minority high school students from Trenton High School. In addition, the equipment will be used in on-campus collaboration with Princeton Energy Center and inter-university collaboration with the Plasma Research Center in Drexel University.
