In the context of fluid mechanics, multiphase flows can be taken as simply any fluid flow system consisting of two or more distinct phases flowing simultaneously in mixture, having some level of phase separation at a scale well above the molecular level. ...

Two-phase flow through hydrocarbon or geothermal wells can be categorized as non-boiling problems (Tang and Ghajar, 2011). There are several studies on developing correlations for void fraction and frictional pressure losses in wells and pipes. Some of these studies (e.g. Orkiszewski, 1967; ...

across flow domain. Solutions are typically plots of velocity vectors, streamlines, pressure contours (and temperature contours if energy equation is added). These may be processed to produce such data as forces (eg lift and drag on a foil) or pressure loss in pipes and fittings. Computational...

Introduction Bent pipes and elbows are used in many engineering systems, including water supply systems, oil and gas piping systems, automobile engines, power generation plants, turbo ...
As a technology of transporting solid materials through the flow of fluid in closed pipes, transportation plays an important role in the solid processing industry. The key to reducing transportation loss is to explore the law of internal flow in the pipeline and carry out transportation design, co...
In this section, we have focused on real or virtual pipes of finite dimension, but we can also shrink the pipe to an infinitesimal dimension until it basically coincides to a single streamline. This way, we could extend the principle of conservation of the fluid flow rate to any continuous ...
A controllable gas-lift well having controllable gas-lift valves and sensors for detecting flow regime is provided. The well uses production tubing and casing to communicate with and power the control
