Hydrodynamic and statistical parameters of slug flow
In two-phase slug flow pattern, the bulk of the gas is trapped inside large bubbles that are separated by liquid slugs, which may contain small dispersed bubbles. The unsteady nature of slug flow makes the prediction of pressure drop and heat and mass transfer a difficult task. Earlier models that deal with steady slug flow assume constant lengths and shapes of liquid slugs and elongated bubble...

gradual erasure of subjectivity: a study of samuel beckett’s trilogy in the light of postmodernism
ساموئل بکت بیشتر از هر نویسنده دیگری در نیم? دوم قرن بیستم با گفتارش زمان? ما را به آستان? از هم پاشیدگی کشانده است، آستانه ای که در آن مدرنیته با سرانجام گریزان اما غیرقابل اجتناب خود مواجه می شود. در این تحقیق روی مفهوم فردیت و محو آن در دوران پسامدرن تاکید شده و در طی آن سعی شده است که فردیت مدرن و پسامدرن در رمان های سه گانه بکت بررسی گردد. تحقیق حاضر یک بررسی کتابخانه ای و کیفی بر روی سه ر...
15 صفحه اولEvolution of hydrodynamic and statistical parameters of gas–liquid slug $ow along inclined pipes
The development of slug $ow along two 10 m long inclined pipes (2–90◦ from the horizontal) with internal diameters of 0.024 and 0:054 m was measured by three optical 4ber probes. The probes were located in a measurement module at axial distances of 0:020 m between the 4ber tips. To measure the evolution of slug $ow, the module was placed at di6erent positions along the pipe. Instantaneous elong...
متن کاملThe Indication of Two-Phase Flow Pattern and Slug Characteristics in a Pipeline Using CFD Method
Multiphase flows are commonly encountered in oil and gas industries. The transport of multiphase flow causes the formation of slug, the increase of pressure drop and the possibility of phase changes therefore, a set of simulation runs was performed to predict flow regimes in a horizontal pipeline, and the results were compared with the Baker chart. The effects of small downward inclinations of ...
