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.
