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.

摘要Collicott Purdue University CTS-9501881 将进行稳态和脉冲雾化孔流的内部空化和湍流实验研究。 提出了非侵入式短脉冲光学诊断的应用，以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基于光致变色染料的流量标记方法。 将用短脉冲全息照相术和一个间隙尺寸与现代柴油机喷油器喷嘴尺寸相当的特殊孔板来研究孔板流中的空穴现象。 这项工作的应用包括现代多孔柴油机燃料喷射器，喷涂涂料和其他涂层的应用，以及农业喷雾应用。 教学计划包括一个新的程序与编辑和写作任务。 工程专业学生的一个常见的绊脚石是需要将他们的数学知识从早期课程的方程求解格式转移到美味，丰富的工程风味。 一系列简短的文章，以指导学生通过这一过渡的设想。
