| Abstract: | 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. |
