The 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 ...
متن کاملPulsatile pressure-flow relations and pulse-wave propagation in the umbilical circulation of fetal sheep.
The relations between pulsatile pressures and flows in the umbilico-placental circulation have been investigated using chronically instrumented fetal sheep. Under resting conditions, mean arterial pressure fell by 30 +/- 6%, from 44 +/- 2 to 31 +/- 2 mm Hg between the aortic termination and the arteries feeding the cotyledons, and pressure waves were substantially damped during propagation betw...
متن کاملPulse pressure, blood flow, and atherosclerosis.
B lood vessels are exposed to two kinds of dynamic mechanical forces. One of them is shear stress and the other is the cyclic strain of the vascular wall, which, according to the Laplace’s law, is mainly determined by cyclic change of blood pressure (BP). While shear stress directly affects endothelial cells, BP changes (and the resulting changes in arterial wall strain) influence all structure...
متن کاملTwo Phase Flow Pressure Drop Calculation Using Homogeneous Equilibrium Model
Although two-phase flow is frequently encountered in various location of the process plants, there is no a general accepted and verified two-phase flow model that may be used to size lines for such conditions. An obvious example is condensate water return lines. The API method that used in this study is based on the homogeneous equilibrium flow assumption, that is, equal velocity and equal temp...
متن کاملNumerical Computation Of Multi-Component Two-Phase Flow in Cathode Of PEM Fuel Cells
A two-dimensional, unsteady, isothermal and two-phase flow of reactant-product mixture in the air-side electrode of proton exchange membrane fuel cells (PEMFC) is studied numerically in the present study. The mixture is composed of oxygen, nitrogen, liquid water and water vapor. The governing equations are two species conservation, a single momentum equation for mobile mixture, liquid mass cons...
