摘要

本文研究了明渠流中两种垃圾架(或网)组合的能量耗散率。五个垃圾架组件将水槽分成下游方向的四个相同的水池。将流动的整体特征与在流动的水柱中进行的Tomo-PIV测量进行了比较。从Tomo-PIV测量中，可视化了流动中的瞬时结构，并分析了湍流动能的衰减和能量耗散。

VOLUMETRIC MEASUREMENTS BY TOMOGRAPHIC PIV OF GRID GENERATED TURBULENCE IN AN OPEN CHANNEL FLOW

This paper investigates the energy dissipation rate behind two combinations of trash racks (or meshes) in an open channel flow. Five trash rack assemblies divided the flume into four identical pools in the downstream direction. The global characteristics of the flow were compared with Tomo-PIV measurements that were taken in the water column of the flow. From the Tomo-PIV measurements, the instantaneous structures in the flow were visualised and the decay of turbulent kinetic energy and energy dissipation analysed.
