In this work we propose an effective viscosity criterion for the stabilization of annular gas-liquid and liquid-particle flows and an inertial mechanism which drives waves into slugs in slugging gas-liquid flows. Annular flow is stable when the fluid having the higher effective viscosity occupies the core region and the lower viscosity fluid is the annulus. The eddy viscosity criterion is shown...

This work investigates the impact of elevation on terrain-induced slugging in a riser system. Fluid compositions were modeled with multiflash and exported to OLGA readable PVT Table File. Pipeline materials properties geometry different develop flowline model. Two geometries (1 2) elevations defined establish their effect accumulated liquid volume flow, surge volume, slug length, number slugs d...

Valsartan is a FDA approved drug for the treatment of hypertension belongs to a class of drug known as angiotensin II receptor antagonists, which helps to control high blood pressure. Angiotensin II is a substance in the body that increases blood pressure. Valsartan works by blocking the effect of angiotensin II, as a result, blood vessels relaxes and blood pressure is lowered. The aim of the p...

Process measurements are of vital importance for monitoring and control of industrial plants. When we consider offshore oil production platforms, wells that require gas-lift technology to yield oil production from low pressure oil reservoirs can become unstable under some conditions. This undesirable phenomenon is usually called slugging flow, and can be identified by an oscillatory behavior of...
