Slugging flow regime
WebbThe PIPESIM simulator produces detailed flow regime maps at points of interest. The design of pipelines and processing facilities can be optimized by predicting hydrodynamic slugs, including size and frequency, as a function of length traversed. Additionally, the PIPESIM simulator predicts the risk of severe slugging in risers. Webb8 maj 2024 · This study focused on gas/Newtonian and gas/non-Newtonian two-phase horizontal fluid flow behavior by analyzing their flow regime identification and flow structural analysis on a horizontal flow loop apparatus. This involved the recognition of two-phase flow regimes for this flow loop and validation with existing flow maps in the …
Slugging flow regime

WebbScienceDirect WebbFor the tests leading to a slugging regime, i.e., for low aeration flow rates, the measured velocities are in good agreement with the two-phase theory. However, for the turbulent and fast fluidization regimes, the measured velocities are higher than 1 m/s i.e., higher than the value estimated with the theory for the slugging regime which confirms the regime …
WebbThe selection of the pipeline was based on the pressure drop and flow regime . Severe slugging was a major problem observed during simulation due to the hilly terrain nature of the seabed. If not mitigated slugging would reduce the efficiency of the separator therefore utilising the use of a riser top valve choking combined with gas lifting has shown … WebbThe slug flow (or slugging) regime arises in gas-fluidized beds when bubbles grow sufficiently large that their shapes and rising velocities are mainly determined by the diameter of the column in which they are found. Two types of gas slugs are encountered in fluidized bed studies and applications: round-nosed slugs and square-nosed slugs.
WebbSlug flow : at higher gas velocities, the diameters of the elongated bubbles become similar in size to the channel height. The liquid slugs separating such elongated bubbles can also be described as large amplitude waves. Figure 2: Some flow patterns in horizontal pipe. 3.1.1 Detection of flow regime Webb12 apr. 2024 · In this paper, a pitching NACA 0012 airfoil is simulated in the slip flow regime by solving the Navier–Stokes equations subjected to the Maxwell slip and Smoluchowski jump boundary conditions. The rhoCentralDyMFoam solver of the OpenFOAM software has been modified to handle these boundary conditions. The …
WebbROSEN can devise strategies to eliminate or minimize slugging, improve topsides stability and ensure maximum production during Life of Field operation. Typical studies include: Extensive multiphase transient simulations to determine the type and tendency of slugging; Development of a flow regime envelope for Life of Field operation
