Investigating the transition boundary and frequency characteristics of severe slugging under
different riser heights and pipeline lengths provides important support for the expansion of …

Severe slugging produces huge fluctuations of pressure and flow rate, which is often
eliminated by choking because of its easy operation and good performance. However, most …

It is an important function of submarine pipeline flow assurance system to monitor
undesirable gas-liquid flow patterns in pipeline in real time, and release early warning …

This paper reports the experimental results of the severe slugging (SS) flow characteristics
in a downward inclined pipeline-catenary flexible riser system. The non-intrusive optical …

This paper reports the experimental results of the vibration response of a hybrid riser
conveying severe slugging. The hybrid riser comprises a vertical rigid riser made of a …

An experimental study is performed for investigating riser responses under flow-induced
vibration (FIV) of a flexible riser transporting spiral flow and straight flow in a large-scale …

The vortex-induced vibration of a catenary flexible riser hinged underneath a two-degree-of-
freedom horizontally oscillating platform is experimentally investigated in this work. The …

The vortex-induced vibration (VIV) in relation to a flexible pipe is numerically studied in order
to examine the coupled effects occurring between the external shear current and the varying …

The intrinsic characteristics of multiphase flow inevitably result in vibrations within the pipe
structure. The evolution of vibration characteristics is crucial for monitoring the stability of the …

It is essential to study the influence of pipeline structure on flow pattern distribution and void
fraction in riser systems to ensure the safe and stable operation of offshore pipelines. This …
