Abstract
The horizontal two-phase flow, especially slug and bubbly flows, are preferably used in various industrial applications because it provides high interfacial areas which enhance the heat and mass transfer. Moreover, the two-phase flow rate measurements remain a challenging task due its complexity. There are many factors that affect the measurement process such as the properties of the two phases and the dryness fraction. In the present study, the phase distribution of controlled air-water flow in a horizontal acrylic circular pipe with 60 mm inner diameter (D) has been investigated experimentally and modeled numerically. The modeled differential pressure and the mixture velocity profile at a distance of 33D from the mixing section (fully-developed region) are computed numerically and compared with those obtained experimentally from the two-phase flow system established and maintained at the National Institute of Standards (NIS-Egypt). The numerical and the experimental data have been compared with previous correlations and models. Reasonable quantitative agreement between all data is found. An electronic device based on Arduino UNO board was designed and used with careful data manipulation for measuring the slug bubble velocity.
