Optical instrumentation toward resolving mixing in micro-channels

_纳米和微米尺度上的流动是广泛系统的行为和性能的基础（例如，膜过滤、毛细血管血流和储油层），了解这些流动对于这些领域的发展至关重要。拟议的实验研究将应用测量科学的最新思想和技术来解决这些问题，特别是这些小尺度上混合过程的特征。将开发基于显微镜的成像技术，以测量作为时间（1D）函数的三维空间（3D）上的流的速度（3C）的三个分量。主要目的是推导出全时间分辨速度场（3C4D），这些技术也将被扩展到测量流的标量属性，以解决混合。这种类型的数据可用于研究新现象，验证数学模型和推进当前纳米和微器件的设计。因此，该计划的总体目标是开发基于图像的测量技术科学，用于解决纳米和微流体流动中的流体混合。作为这项建议的一部分，将利用阿尔伯塔大学在纳米和微流体流动领域的强大合作研究团体，从而为正在开发的技术建立直接的相关性。这项工作将有更广泛的影响，通过使用开发的技术来量化流动现象，流动建模和设备设计。HQP的开发和培训是该计划的重要组成部分，无论是在开发HQP的知识和技能，还是为了该计划的成功。研究工作是多学科的，涵盖工程设计，光子学和光学系统，测量科学和纳米和微流体学领域，以及提高学生的项目管理和沟通技能。参与该项目的HQP将有一个合作的经验，这将是一个积极的开始，他们的研究生涯。

_Flows on the nano and micro-scales are fundamental to the behavior and performance of a broad range of systems (e.g., membrane filtration, capillary blood flow and oil reservoirs), and understanding these flows is crucial to advancement in these fields. The proposed experimental research will apply the latest ideas and techniques in measurement science to these problems, in particular the characterizing of mixing processes on these small scales. Imaging techniques based on microscopy will be developed to measure the three components of velocity (3C) of the flow over the three dimensions of space (3D) as a function of time (1D). Principally aimed at deriving the full time resolved velocity field (3C4D), these techniques will also be extended to measure scalar properties of the flow in order to address mixing. Data of this type can be used to investigate new phenomenon, validate mathematical models and advance designs of current nano- and micro-devices. The overall aim of the program is therefore to develop the science of image-based measurement techniques for resolving fluid mixing in nano- and micro-fluidic flows._As part of this proposal, the strong collaborative research community in the area of nano- and micro-fluidic flows at the University of Alberta will be tapped into, thereby establishing immediate relevance for the techniques being developed. The work will have broader impact by using the developed techniques to quantify flow phenomena, flow modeling and device design. Development and training of HQP is an important part of the program, both in development of knowledge and skills of the HQP and for the success of the program. The research work is multidisciplinary covering the areas of engineering design, photonics and optical systems, measurement science and nano- and micro-fluidics, as well as improving the students' project management and communication skills. HQP involved in the project will have a collaborative experience that will be a positive start to their research careers.
