Engineering Research Equipment Grant: Four-Beam Two-Color Laser Doppler Anemometer System

在单个速度分量不足以描述感兴趣的现象的实验中，添加双色激光风速计将提供瞬时速度矢量测量。这包括声学驱动的脉冲燃烧、对称物体的“无动量”尾迹以及声场强化飞灰凝聚。这项研究与工业设计目标的相关性是巨大的。更好地控制燃烧，特别是在非稳定流动中，将在推进或加热设备中产生更高的效率，并增强冷凝危险或麻烦的副产品(飞灰)的能力。建议提供57150美元的资金，宾夕法尼亚州立大学另外提供57150美元的费用分摊。

The addition of a two-color laser anemometer will provide an instantaneous vectorial measurement of velocity in experiments where single velocity components are inadequate to describe the phenomenon of interest. Such are acoustically-driven pulsed combustion, "momentumless" wakes of symmetrical objects and the intensification of fly ash agglomeration by acoustic fields. The relevance of this research to industrial design goals is substantial. Better control of combustion, especially in unsteady flows, will yield better efficiency in propulsion or heating devices, with an enhanced capability to condense dangerous or troublesome by-products (fly ash). Funding of $57,150 is recommended, to be cost-shared by an additional $57,150 from Pennsylvania State University.
