“…Therefore, it is pertinent to obtain time varying measurements of the impact and some slug characteristics, including slug velocity, liquid hold-up and pressure at the inlet and outlet of the bend that contribute to this impact. It has been shown that isolating the bend from the upstream and downstream pipe works is vital (Tay and Thorpe, 2002, 2004, 2014Fairhurst, 1983;Hargreaves and Slocombe, 1998). The experimental data discussed in this paper was collected from the same experimental rig used by Tay and Thorpe (2002, 2004, 2014.…”

“…Following this, the control surfaces of analysis were placed through the 3 mm gaps in the bellows to eliminate the force in the pipe metal (F stress ). Ideally, pressure at these locations should be measured in order to be able to calculate the pressure-area terms as proposed by Tay and Thorpe (2002, 2004, 2014 in their Piston Flow Model (PFM):…”

“…3. This setup reduced the disturbance on the main stream due to the sudden increase and decrease in the flow area and eliminated the disturbance on the mainstream due to the corrugated surface of the bellows (Tay and Thorpe, 2014). The bend was fixed onto the preload set with a quartz force sensor (Kistler, 9167A1.5) clamped in between.…”

“…This sensor contains quartz rings that are sensitive to shear and so measures the force components F x and F y . Continuous measurement of x-and y-component forces is possible to give time-dependent force traces with an effectively instantaneous response time; the data points were recorded every 10 ms. Tay and Thorpe (2002, 2004, 2014 set up their experimental rig based on their defined control volume analysis of a horizontal pipe bend as shown in Fig. 4.…”

The impact forces caused by gas-liquid slug flow can lead to the vibration of process system or fatigue failure of pipe fittings. In this study, a piston-flowmodel coupling with slug model is developed to calculate the impact forces, which can contribute to the structure design and flow assurance. An experiment installation is installed to study the characteristics of slug flow and validate the reliability of the model. The accuracy of this model is above 90% for the superficial velocity of gas below 2 m/s, whereas the average deviation is 29.2% for the cases of superficial velocity of gas above 2 m/s. The modified model addressing the liquid holdup agrees well with the experimental data, of which the average deviation is 6.25%.

The dynamic behaviors of a horizontal piping structure with an elbow due to the two-phase flow excitation are experimentally investigated. The effects of flow patterns and superficial velocities on the pressure pulsations and vibration responses are evaluated in detail. A strong partition coupling algorithm is used to calculate the flow-induced vibration (FIV) responses of the pipe, and the theoretical values agree well with the experimental results. It is found that the lateral and axial vibration responses of the bend pipe are related to the momentum flux of the two-phase flow, and the vibration amplitudes of the pipe increase with an increase in the liquid mass flux. The vertical vibration responses are strongly affected by the flow pattern, and the maximum response occurs in the transition region from the slug flow to the bubbly flow. Moreover, the standard deviation (STD) amplitudes of the pipe vibration in three directions increase with an increase in the gas flux for both the slug and bubbly flows. The blockage of liquid slugs at the elbow section is found to strengthen the vibration amplitude of the bend pipe, and the water-blocking phenomenon disappears as the superficial gas velocity increases.
