Two-phase annular flow in vertical pipes is one of the most common and important flow
regimes in fluid mechanics, particularly in the field of building drainage systems where …

In this study, the influence of U-bends on the flow and pressure propagation characteristics
of a gas–liquid two-phase flow in upstream and downstream straight pipes was investigated …

Pressure drops in horizontally aligned U-bends were measured for air-water bubbly, plug,
slug and annular flows to examine the applicability of available correlations to the data. The …

Gas-liquid two-phase flow in curved channels is widely found in various heat exchangers
and transport pipes. The fluid flow and heat transfer characteristics are closely related to flow …

The objective of this work is to study the flow behavior and oil film thickness in the vertical
helical channel to improve the efficient operation of the single screw expander. The volume …

The need to understand the flow behavior and film thickness in the single screw expander is
very crucial since it is known to be a complex system due to the existence of various flow …

This paper presents an experimental and numerical study of gas-liquid annular flow in
horizontal 180 U-bends. The paper aims to study the effect of bend curvature radius and …

A detailed insight into the liquid film characteristics in the helical channel of single screw
expander is of great significance for avoiding the leakage loss of higher pressure gas to …

Annular flow is predominant in gas wells. Liquid may be present in form of entrained
droplets as well as in the liquid film on pipe wall. The knowledge of the average liquid film …

In this work, the two-phase flow frictional pressure drop of a refrigerant flow up-and
downstream of a sharp return bend is studied. The radius of the return bend is 10.2 mm and …
