Acquisition of a Laser Doppler Velocimeter for Non-Intrusive Flow Measurements

建议编号：CTS 9977265首席研究员：H.Johari这项重大研究仪器(MRI)奖支持收购双组分光纤激光多普勒测速仪(LDV)系统，以及精确的三轴横移系统，用于逐点测量水和气态流动中的速度场。LDV系统将用于几个正在进行的基础研究项目，从超音速流动中过热液滴的研究到不可压缩流动中充气降落伞伞盖的流动。这些研究项目涉及研究生和本科生层面的跨学科研究活动。LDV系统还将大大增强伍斯特理工学院机械工程系航空航天和流体力学实验室未来的研究和研究生培训能力。

Proposal Number: CTS 9977265Principal Investigator: H. JohariThis Major Research Instrumentation (MRI) award supports the acquisition of a two-component fiber-optic Laser Doppler Velocimeter (LDV) system, along with a precise three-axis traversing system, for pointwise measurements of velocity fields in aqueous and gaseous flows. The LDV system will be utilized in several ongoing fundamental research projects ranging from the study of superheated droplets in supersonic flow to the flow around an inflating parachute canopy in incompressible flow. These research projects involve interdisciplinary research activities at both graduate and undergraduate levels. The LDV system will also significantly enhance the future research and graduate student training capabilities of the Aerospace and Hydrodynamics Laboratories in the Mechanical Engineering Department at Worcester Polytechnic Institute.
