“…Sahand et al designed a new multiphase flowmeter by coupling a slotted orifice plate with a swirl flowmeter, and evaluated the performance with high-accuracy two-phase flow measurements (Sahand et al (2014)). In addition, other all kinds of flow characteristics has also been deeply studied (Cheng et al (2020), Zhang et al (2019), Chen et al (2016), Cui et al (2015), Bilicki et al (2002), Kock and Herwig et al (2004), Tao et al (2020), Cui et al (2020), , , Jia et al (2022), Jia et al (2022), ).…”
