为了解决微管道(水力直径小于1 mm)内流量测量问题,采用Micro-PIV对水力直径为230 μm毛细玻璃管内流量进行测量.实验中对Re=480～2 260范围内流量进行测量,试验结果证明利用该技术完全可能实现微管道内流量精确测量.%In order to solve the problem of measuring the flow rate in microtubes (the hydraulic diameter is under lmm) ,the Micro-PIV is used to measure the fiowrate within the capillary tube,and its hydraulic diameter is 230μm.In the experiment,the fiowrate is measured in the reynolds number range of 480 ～ 2260,and the conclusion is that Micro-PIV technique can be used to measure the fiowrate in the microtubes with high precision.
