项目摘要

ABSTRACTProposal No. CTS-0421561Principal Investigator: P. W. Fontana, Seattle UniversityThis grant is for acquisition of a laser Doppler velocimetry (LDV) system for use in turbulence research in the Fluid Turbulence Laboratory at Seattle University. The initial investigations in which this instrument will be used involve the phenomenon of sheared flow suppression of turbulence. This phenomenon is not yet fully understood, but is believed to be responsible for the restriction of airborne particulates from volcano eruptions from entering or leaving the equatorial jet, the persistence of the ozone hole in the South Polar vortex, and the good confinement seen in the best fusion reactor discharges. This experiment will be a study of sheared flow suppression of turbulence in a controlled and comprehensive way by inducing turbulent sheared flows in suspended surfactant layers and directly measuring the effects of the shear on transport. Analysis of the results will enable the first systematic quantitative comparison of experimental data with the emerging theory. The LDV is an essential diagnostic for this research because it will provide the time-resolved data needed to analyze the dynamics of the flow. The instrument will significantly broaden the scope and impact of the results to be achieved in these experiments. The LDV is also versatile, and will continue to be a central element of the laboratory as the research expands beyond these initial experiments. This research is motivated by and has direct bearing on current issues in fusion energy research. The pursuit of this limitless source of clean energy has become a renewed national and international priority. Seattle University is a primarily undergraduate institution, so this project will afford undergraduates an opportunity to participate at the frontiers of science. The teaching curriculum will also benefit from the presence of this state-of-the-art LDV system, and the laboratory will promote recruitment of highly-qualified students in the sciences and engineering. The university and its College of Science and Engineering have large enrollments of underrepresented groups and women, so these groups particularly will gain from the research opportunities and teaching enhancements promised by this project.
摘要建议编号 CTS-0421561主要研究者: P. W.丰塔纳,西雅图大学这笔赠款是用于购买激光多普勒测速(LDV)系统用于湍流研究在流体湍流实验室在西雅图大学。使用该仪器的初步研究涉及湍流的剪切流抑制现象。 这一现象尚未被完全理解,但据信是火山爆发产生的空气颗粒进入或离开赤道急流的限制、南极涡旋中臭氧空洞的持续存在以及最好的聚变反应堆放电中所见的良好限制的原因。该实验将通过在悬浮表面活性剂层中诱导湍流剪切流并直接测量剪切对输送的影响,以受控和全面的方式研究湍流的剪切流抑制。 对结果的分析将使实验数据与新兴理论的首次系统定量比较成为可能。 LDV是这项研究的重要诊断工具,因为它将提供分析流动动力学所需的时间分辨数据。 这一工具将大大扩大这些实验所要取得的成果的范围和影响。 LDV也是多功能的,并将继续成为实验室的核心元素,因为研究扩展到这些初始实验之外。 本研究的动机和直接关系到当前聚变能研究的问题。 追求这种无限的清洁能源已成为国家和国际的新优先事项。 西雅图大学是一个主要的本科院校,所以这个项目将为本科生提供一个参与科学前沿的机会。 教学课程也将受益于这种最先进的LDV系统的存在,实验室将促进科学和工程领域高素质学生的招聘。 该大学及其科学与工程学院招收了大量代表性不足的群体和妇女,因此这些群体将特别受益于该项目所承诺的研究机会和教学改进。
