Eccentric core-annular flow is encountered in water-lubricated transport of highly viscous oil
in horizontal pipes. The core eccentricity results from the tendency of the phases to stratify …

In evaporators and condensers of refrigeration and air conditioning systems, various straight
tubes are joined via U-bends. These U-bends result in higher pressure drops due to flow …

This study reports numerical results for the flow of two initially perfectly mixed but immiscible
liquids in helical and straight pipes, with a view toward optimal separation. Different flow …

Air handling units in refrigeration systems have U-bends that significantly affect pressure
drops but have little impact on heat transfer. This study experimentally investigated the two …

This study used the Ansys Fluent® computational fluid dynamics code in conjunction with a
volume of fluid multiphase model and phase‐change model to analyze the flow boiling …

The economic and engineering importance of additive drag reduction (DR) has provided
motivation and wealth of data on the phenomena in straight conduit flows. Study into the …

In this paper, a systematic numerical study of the local resistance coefficients of vertical L‐
shaped and Z‐shaped pipes for gas‒liquid two‐phase flows under vertical conditions was …

Drag reduction (DR) by additives in single-and two-phase fluid transport has enormous
engineering and economic benefits. An ample amount of work has been done with regards …

In this era of scarce and expensive energy, it has become imperative to devise means of
reducing energy consumption, particularly in petroleum industries where huge amounts of …

The current work presents an experimental demonstration of the impact of two-phase flow
mixture (water and air) temperature on the pressure across the bend's upstream and …
