报告摘要：

  Phase change is encountered in manyimportant industrial processes and systems. Despite the numerous experimentalstudies of relevant flows, the availability of spatiotemporally-resolvedsimultaneous information on the underlying physical phenomena remains limiteddue to the challenges in performing such measurements.

  These flows present the experimentalistwith unique challenges, such as restricted (often sub-mm) fluid domains withmoving and complex interfaces, across which phases have large property changes.Experimental techniques based on optical measurement principles can be applied,but further development is necessary for reliable data to be obtained. Oncedeveloped, these techniques can provide information with high spatiotemporalresolution on important scalar and vector fields in relevant flows, as well ason interfacial characteristics and dynamics.

  In this talk, we will present recent efforts todevelop and apply a range of infrared, laser-based and other optical diagnostictechniques to flows with phase change and reaction. We will cover thedeployment of simultaneous techniques for the generation of new multiphysicsand multiscale information, and discuss challenges faced when attempting suchmeasurements. This information is enabling an increasingly complete fundamentalunderstanding of related phenomena, and the improved design of relevantdevices, technologies and systems.
