3-Component Velocity Measurement over 4-Dimensions

本提案旨在开发一种适用于激光照射和自发光物体的方法，用于在四维场上连续测量三分量速度。目前还没有技术可用于研究时变微流体系统或4D气相流。提出的仪器是基于沿单线访问的图像平面测量，其中该图像受非轴对称像差的影响。该方法将应用于以下领域的流动结构发展图：解决摩擦基本问题的微致动器泵设计，用于构建100毫米以下间距的碰撞芯片的新制造工艺，以及与汽车发动机混合物制备相关的气相流动。

This proposal seeks to develop a method applicable to both laser-illuminated and self-luminous objects for 3-component velocity measurement on a continuous basis across a 4-dimensional field. No techniques are currently available for the study of temporally varying microfluidic systems or 4D gas phase flows. The proposed instrumentation is based on an image plane measurement along a single line of access, where that image is subject to nonaxially-symmetric aberrations. The method will be applied to map flow structure development in: micro-actuator pump designs addressing the fundamental issue of friction, novel manufacturing processes for the construction of sub 100mm pitch bumped chips and to gas phase flows relevant to mixture preparation in automotive engines.
