WebAug 1, 2001 · This paper introduces the TERT-II prototype developed in Tianjin University and the process by which we applied it to identify flow regimes of air/water and oil/water flows in horizontal, inclined and vertical pipes. The corresponding software package of this system was developed under the Windows 95/98 platform. Web2. n. [Production Logging] A multiphase-flow regime in pipes in which most of the lighter fluid is contained in large bubbles dispersed within, and pushing along, the heavier fluid. The word slug normally refers to the heavier, slower moving fluid, but sometimes to the bubbles of lighter fluid. There are also small bubbles within the liquid, but many of these have …
WebMar 15, 2024 · This behavior is often termed the flow regime. The most common regimes are laminar, turbulent, and transitional. Unfortunately, it is impossible to clearly define each type in the weil. As an example, mud flow may be predominantly laminar, although the flow near the pipe walls during pipe rotation may be turbulent. Laminar Flow. WebFlow regimes represent typical flow patterns exhibited by fluids as they flow under differing conditions. Reynolds number is used to describe the boundaries of flow regimes; however care must be taken as there are other factors which may influence the flow regime of a fluid. ... In the case of a straight, non-smooth pipe the flow regimes and ...

WebMar 5, 2024 · The dimensionless Reynolds number is used to classify the state of flow. The Reynolds Number Demonstration is a classic experiment, based on visualizing flow behavior by slowly and steadily injecting dye into a pipe. This experiment was first performed by Osborne Reynolds in the late nineteenth century. 2. Practical Application.
WebApr 6, 2024 · Subsea jumpers connecting the underwater wellhead and nearby manifold commonly undergo flow-induced vibration (FIV) due to the spatially frequent alteration in the flow direction, velocity, pressure and phase volume fraction of the oil–gas two-phase flow, potentially leading to fatigue damage.
