Performance of an Orifice Meter Handling Two-Phase (Gas-Liquid) Flow.(Dept. M)

Simulation of gas-liquid two phase flow in upriser pipe of gas-lift systems

Gas-lift pumps are devices for lifting liquid phase incorporating the gas phase to be injected in the bottom of liquid column. They are widely used in various industrial applications such as oil extracting in petroleum industries. Gas-liquid flow being the main part of the flow through these systems, flowing in vertical pipes of gas-lift pumps has different regimes namely bubbly, slug, chur...

Comparison of the hyperbolic range of two-fluid models on two-phase gas -liquid flows

In this paper, a numerical study is conducted in order to compare hyperbolic range of equations of isotherm two-fluid model governing on two-phase flow inside of pipe using conservative Shock capturing method. Differential equations of the two-fluid model are presented in two forms (i.e. form I and form II). In forms I and II, pressure correction terms are hydrodynamic and hydrostatic, respecti...

Correcting a Coriolis Meter for Two Phase Oil & Gas Flow

It is also common for flowmeters to be installed downstream of a two or three phase separator. If the well conditions change or the separator has been incorrectly sized, then it is possible that the oil liquid outlet may have some gas carry under. The effects of gas entrainment on the output of ultrasonic and Coriolis meters has been reported previously [1] [2]. It is already known that gas ent...

Phase characterization of experimental gas–liquid two-phase flows

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
