Localized Mixing Zone for Muskat Bubbles and Turned Interfaces

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. ...

Waves and Mixing in the Coastal Zone

As part of our project entitled Wind, Waves, and Mixing in the Coastal Region (AO3-379) some measurements of waves and current profiles were performed in our study site. In the Pacific coast of Baja California, a wave and current sensor, a marine radar and a meteorological station have been in operation since mid 1998. Additionaly, a current meter profiler (adp) was installed for some days in e...

افزونگی قاب های موضعی (redundancy for localized frames)

نشان میدهیم افزونگی یک ویژگی کیفی است که قاب های فضای هیلبرت را در کاربرد مفید می سازد. با این حال بدست آوردن یک تعریف کمی معنی دار از افزونگی برای قاب های نامتناهی پیچیده است ولی از آن جایکه جایگزین هایی برای افزونگی موجود است مهمترین مساله باز این است که ایا یک قاب با افزونگی بزرگتر از یک دارای یک زیر قاب با افزونگی دلخواه نزدیک به 1 هست یا نه ؟ ما به این سوال برای قاب های موضعی شده جواب مثب...

Visual Plumes mixing zone modeling software

The US Environmental Protection Agency has a history of developing plume models and providing technical assistance. The Visual Plumes model (VP) is a recent addition to the public-domain models available on the EPA Center for Exposure Assessment Modeling (CEAM) web page. The Windows-based VP adapts, modifies, and enhances the earlier DOS-based PLUMES with a new interface, models, and capabiliti...
