The characteristics of multiphase fluid flow in pipes are useful to understand fluid dynamics encountered in the oil and gas, chemical and production industries. During the transport of different types of fluid, understanding the hydrodynamic behavior inside the pipe network is important for flow assurance. The presence of relative agitation in the interfaces and inconstant interactions among distinct phases, multiphase flow becomes a complex conveyance phenomenality in contrast to single-phase flow. This study is focused on gas/Newtonian and gas/non-Newtonian two-phase horizontal flow structure. This investigation ranges from analyzing volume fraction, pressure drop, flow regime identification, flow structure analysis, etc. This involves recognition of the two-phase flow regimes for this flow loop and validates it with the existing flow maps in the literature. In another study, slug frequency has been examined and compared with air/Newtonian and air/non-Newtonian fluid in the flow loop. Finally, wavelet packet transformation is used to decomposition pressure signals for different flow pattern.
