Slugging flow regime
In fluid mechanics, slug flow in liquid–gas two-phase flow is a type of flow pattern. Lighter, faster moving continuous fluid which contains gas bubbles - pushes along a disperse gas bubble. Pressure oscillations within piping can be caused by slug flow. The word slug usually refers to the heavier, slower moving fluid, … Visa mer • Production of hydrocarbon in wells and their transportation in pipelines;. • Production of steam and water in geothermal power plants. • Boiling and condensation in liquid-vapor systems of thermal power plants; Visa mer • Slip ratio (gas–liquid flow) • Slugcatcher • Plug flow • Two-phase flow Visa mer http://drbratland.com/PipeFlow2/chapter1.html

In vertical flow, the … WebbAbstract: A fluid-structure interaction model for a marine riser system on elastic foundation conveying severe slugging flow was developed based on the modified severe slugging transient model and theories of plane frame structure, and solved to simulate the dynamic response of a marine riser system caused by severe slugging flow using numerical …
WebbBehind the interface, only displacing fluid is flowing, in the presence of immobile oil at its residual saturation. The following describes the method of calculation for segregated flow displacement, as outlined by Dake 1. Calculate the endpoint mobility ratio, from the following : Calculate the dimensionless gravity number, from the following ... Webb9 apr. 2024 · In the kinetic theory of gases, two asymptotic flow regimes are distinguished: the free molecular regime at \({\text{Kn}} \to \infty \), and the continuum flow regime described by the Navier–Stokes equations at \({\text{Kn}} \to 0\).Between these limiting regimes lies the transient flow regime, in which it is necessary to solve the Boltzmann …
WebbAs well as the vertical slug flow work, the thesis also presents results obtained in testing the models capabilities to simulate two other effects found in two-phase flows in pipes. The first is the hysteresis phenomena found in horizontal pipes, where the point of transition from stratified flow to slug flow and vice versa is found to shift depending on … Webb29 mars 2024 · Slug flow can be classified into two types: terrain-induced and severe slugging. Terrain-induced slug flow happens when the pipeline profile has uphill and downhill sections, creating a natural ...
WebbThe slugging flow of polyethylene particles was analyzed from the measured pressure drop signals by clas- sical statistical methods such as absolute average deviation, probability density function, power spectrum, auto-cor- relation, and cross-correlation.
