“…1 ) which was conducted using a close-loop test rig system utilizing the air-water as prime fluids medium [1] . The air-water closed-loop pipeline is used for a wide range of applications [3] , [4] , [5] , [6] , [7] . The data used for the investigation of three slug characteristics which are the slug length ( Supplementary Table 1 ), slug frequency ( Supplementary Table 2 ), and the slug translational velocity ( Supplementary Table 3 ) are provided to save time and effort.…”

The data presented in this article were the basis for the study reported in the research articles entitled “Statistical assessment of experimental observation on the slug body length and slug translational velocity in a horizontal pipe” (Al-Kayiem et al., 2017) [1] which presents an experimental investigation of the slug velocity and slug body length for air-water tow phase flow in horizontal pipe. Here, in this article, the experimental set-up and the major instruments used for obtaining the computed data were explained in details. This data will be presented in the form of tables and videos.

“…They termed this persistence of frequency. They also found a similar behaviour between the pipe upstream and the throat of a Venturi and in pipeline˗bend˗riser arrangements in the work of , e.g., Saidj et al (2014). This paper is an attempt for understanding the fundamentals of the effect of the orifice on the two-phase flow behaviour through this fitting.…”

“…They presented that the slugannular flow in flow pattern maps shifted towards the higher superficial gas velocities as the height-to-width ratio decreased. Air-water flows through horizontal to vertical through a 90-degree bend were analyzed by Saidj et al [7]. They identified the flow patterns both in the horizontal pipe and the vertical pipe upstream, using the Probability Density Function (PDF) of the time series of the cross sectional averaged void fraction.…”

Experimental studies were conducted on the behaviour of water films in a horizontal pipe with a sudden contraction to achieve a fundamental understanding of the film mechanisms of annular flow using highspeed video imaging analysis. The sudden contraction area ratios AC = (d2 /d1) 2 = 0.36 and 0.64, where d1 is the inlet pipe diameter (50 mm) and d2 is the contracted pipe diameter were examined. The experiments were carried out for various values of superficial gas and liquid velocities. The superficial gas velocity after mixing (jG1) ranged from 18.02 to 24.41 m/s (the calculated velocity from the crosssectional at the sudden contraction was jG2 = 27.98-67.39 m/s) and the superficial liquid velocity (jL1) ranged from 8.62×10 -2 to 1.23×10 -1 m/s (jL2 = 1.35×10 -1 -3.42×10 -1 m/s). Four flow regimes were observed after the sudden contraction, namely, huge-wave (HW), two-dimensional disturbance wave (DW1) which is formed perpendicularly to a pipe axis having a distinct coherence, three-dimensional disturbance wave (DW2) which is formed obliquely to the pipe axis, and bow wave (DW3) which is transitional wave to "Misty wave" from DW2. The disturbance wave occurrence frequencies were studied under various conditions of flow rate combination of air and water. DW2 occurs over wide range of the superficial gas and liquid velocities. As the superficial gas velocity and the superficial liquid velocity increase, two-dimensional disturbance waves change into three-dimensional ones. The wave occurrence frequencies in the pipe with the sudden contraction ratio AC = 0.36 were mostly higher than those in the pipe with AC = 0.64.
