ENGINEERING RESEARCH EQUIPMENT: A One-Component Laser Doppler Velocimeter System for Turbulent Particulate Flows in Hydraulics

由工程研究设备补助金资助的设备将用于研究含沙水流中的湍流。利用激光多普勒测速仪测量流体和颗粒的瞬时速度，可以探测流体-颗粒介质中网格产生的湍流。粒子将与具有相同折射率的流体匹配。悬浮颗粒存在于土木工程和环境工程领域的各种流动应用中。

Funded by an Engineering Research Equipment Grant, equipment will be purchased for use in an investigation of turbulence in sediment-laden flows. Grid-generated turbulence in a fluid- particle medium will be explored with a laser-Doppler velocimeter capable of measuring instantaneous fluid and particle velocities. The particles will be matched to the fluid with the same index of refraction. Suspension of particulates occur in a variety of flow applications in the civil and environmental engineering area.
