| 摘 要： | 针对气—液两相流研究对含气率测量的需求，基于线列阵测量技术原理，设计了一种可移动式线列阵两相流测量传感器，该传感器具有较高的空间分辨率（3 mm）和极高的时间分辨率（2500 Hz），设计了线列阵传感器标定和含气率算法，实现了瞬时二维局部含气率的测量。经过射流冲击试验验证表明：该线列阵传感器结构稳定，基于原始测量数据，采用标定和含气率求解算法，可计算气泡夹带现象在水平截面的平均含气率分布情况。

| Abstract: | Aiming at gas fraction measurement needs of gas-liquid two-phase flow study,a movable wire mesh sensor( WMS)for two-phase flow measurement is designed based on principle of WMS measuring technology. The sensor has high spatial and temporal resolutions which are 3 mm and 2 500 Hz. The calibration and gas fraction algorithm are designed to calculate the instantaneous 2D local gas fraction. The plunging jet experiment verifies that the WMS is stable,and based on the original data,the average void fraction distributions of cross-section bubble entrainment phenomenon are calculated using calibration and void fraction algorithm. |
