Career: Experimental Investigation of the Internal Structures in Atomizing Office Flows

CTS-9501881实验将研究稳态和脉冲雾化孔流动中的内部空化和湍流。提出了一种非侵入式短脉冲光学诊断方法，用于测量和观察小孔内的空化和湍流。主要的诊断工具将是使用短脉冲激光的光致变色染料流标记方法。利用短脉冲全息成像技术和一个与现代柴油喷油器孔口尺寸相当的特殊孔口，研究了孔口流动中的空化现象。这项工作的应用包括现代多孔柴油喷油器、喷油器和其他涂层的应用以及农业喷雾的应用。教学计划包括一个带有编辑和写作任务的新程序。对于工科学生来说，一个常见的障碍是需要将他们的数学知识从早期课程的方程求解形式转移到美味、丰富的工程中。我们设想了一系列简短的文章来指导学生完成这一转变。

ABSTRACT Collicott Purdue University CTS-9501881 Experiments investigating internal cavitation and turbulence in steady and pulsed atomizing orifice flows will be conducted. Applications of non-intrusive shortpulsed optical diagnostics are proposed to measure and observe cavitation and turbulence within small orifices. The primary diagnostic tool will be a photochromicdye-based flow tagging method using a short-pulsed laser. Cavitation in the orifice flows will be studied with short-pulsed image holography and a special orifice with gap dimension comparable with the dimensions of modern diesel fuel injector soifices. Applications of this work includes modern multi-orifice diesel fuel injectors, spray pain and other coating application, and agricultural spray application. The teaching plan consists of a new program with editorial and writing tasks. A common stumbling block for engineering students is the need to transfer their mathematical knowledge from the equation-solving format of early courses to delicious, rich flavor to engineering. A series of brief articles to coach students through this transition is envisioned.
