Velocimetry and Sizing in Multi-Constituent Flows for Full-Field Macro and Microfluidic Applications

我们寻求开发新的光学传感器仪器来表征多组分液体和多相喷雾系统以及相关的混合现象。拟议研究的前提是需要了解汽油直喷(GDI)喷雾和气相之间的详细相互作用，以便产生改进的设计。类似的要求也存在于微流控系统中，特别是多组分混合器。同时测速和颗粒大小数据将在整个区域内获得--这是使用当前技术无法获得的信息。要开发的技术是通用的，如要研究的宏观和微观流体应用所例证。

We seek to develop novel optical sensor instrumentation to characterise multi-constituent liquid and multi-phase spray systems and related mixing phenomena. The premise of the proposed research stems from the need to understand the detailed interaction between a gasoline direct injection (GDI) spray and the gas phase in order to generate improved designs. Similar requirements exist in microfluidic systems, specifically multi-constituent mixers. Simultaneous velocimetry and particle size data will be obtained across a full field - information that cannot be obtained using current techniques. The technology to be developed is generic as exemplified by the macro and micro fluidic applications to be studied.
