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

该主要研究仪器（MRI）奖支持采购双组件光纤激光多普勒测速仪（LDV）系统，以及精确的三轴穿越系统，用于水和气体流动的速度场的点对测量。LDV系统将用于几个正在进行的基础研究项目，从研究超音速流动中的过热液滴到不可压缩流动中充气伞盖周围的流动。这些研究项目涉及研究生和本科生水平的跨学科研究活动。LDV系统还将显著提高伍斯特理工学院机械工程系航空航天和流体动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.
