摘　　要：针对传统阵列式光纤探针在测量气液两相流持气率时存在的点位覆盖不足及对流场造成干扰的问题,提出了一种基于单模光纤探针的气液两相流持气率成像方法。该方法利用单模光纤探针对选定的关键位置进行精确测量,并采用克里金插值算法对未直接测量区域的持气率进行估算,从而实现成像。实验结果表明,在气流量设定为0.2 L/min、0.3 L/min、0.4 L/min和0.5 L/min的情况下,此方法能够生成高质量的持气率图像,成功实现了测量区域内持气率分布的可视化。To address the limitations of traditional array-based fiber probes in measuring gas-holding rate in gas-liquid two-phase flows,such as insufficient spatial coverage and flow field disturbance,a new method for gas-holding rate imaging using single-mode fiber probes has been proposed.This method involves precise measurements at selected key positions using single-mode fiber probes and employs Kriging interpolation algorithm to estimate the gas-holding rate in unmeasured regions,thereby achieving imaging.The experimental results show that under gas flow rates of 0.2 L/min,0.3 L/min,0.4 L/min,and 0.5 L/min,this method can generate high-quality gas-holding rate images,successfully visualizing the distribution of gas-holding rate within the measurement region.
