simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

15 صفحه اولNumerical investigation of upward air-water annular, slug and bubbly flow regimes
In this paper, numerical investigation of upward two phase flow of air-water has been studied. Different conditions of flow regimes including annular, wispy annular, slug, churn and bubbly are simulated based on Hewitt and Roberts map, and a good agreement between the experimental data of the map and the numerical simulation has been observed. Accordingly, a proper CFD model in CFD software of ...
متن کاملStrategies for High Vacuum Dewatering on Paper Machines
The Paper machine vacuum system is an important operation for dewatering of wet web to increase percentage solids in web. There are various models available to assess the influence of vacuum on the above parameters. In this present investigation the steady state model is discussed for estimating optimum vacuum load in flat boxes of Fourdrinier paper machine as the flat boxes are the main compon...
متن کاملUnder-water unidirectional air penetration via a Janus mesh.
Under-water and unidirectional air penetration, viz. air "diode", was effectively achieved on the basis of a composite mesh with Janus wettability. In the aqueous solution, the air bubbles can only pass through the mesh from the hydrophilic side to the superhydrophobic side, whereas they will be blocked from the opposite direction.
