| 摘 要： | 针对传统近红外点对点探头传感器测量存在盲区、数据精度低等问题,提出并设计了一种基于近红外面源传感器的气液两相流相含率测量装置,并对其进行研究。该装置有效减小了近红外光的折射与反射,提高了测量的精确度。通过CFD流体仿真软件模拟了管道内流体的流动状态,并对该装置的结构进行了仿真及优化。在单相流实验的基础上进行气液两相流动态实验,得到了4路近红外信号与相含率的关系,建立了相含率测量模型,数据导入修正模型分析得到的相含率测量相对误差在±3.5%以内。 |

| Abstract: | Aiming at the problems of traditional near-infrared point-to-point probe sensor measurement blindness and low data accuracy, a gas-liquid two-phase flow phase content measurement device based on near-infrared surface source sensor was proposed and designed. The device effectively reduced the refraction and reflection of near-infrared light and improved the accuracy of the measurement. The flow state of the fluid in the pipeline was simulated by CFD fluid simulation software, and the structure of the device was simulated and optimized. Based on the single-phase flow experiment, the dynamic experiment of gas-liquid two-phase flow was carried out, and the relationship between the four-way near-infrared signal and the phase-containing ratio was obtained. The phase-containment rate measurement model was established, and the phase-inclusive rate measurement was obtained by data import correction model analysis. The relative error is within ±3.5%. |
