摘要 基于COMSOL仿真软件,对新型的网丝传感器进行了仿真研究,并针对原油高含水情况下油分相含率检测,优化设计网丝式传感器结构。根据油滴尺寸、网格细分以及重建图像等问题提出了分块多阈值算法。仿真实验表明,基于分块多阈值算法进行图像重建,明显改善图像质量,提高了油分相含量检测精度。 A simulation research on Wire-mesh Sensor （WMS） has been developed by using software COMSOL. Focusing on the oil phase fraction measurement in oil-water two-phase flow with high water holdup,author optimized the WMT sensing electrode arrays and proposed a block multi-threshold algorithm,according to oil droplet size,mesh subdivision,and image reconstruction.The results show that the multi-threshold algorithm can significantly improve the image quality and increase measurement accuracy of oil phase fraction.
