The motion of liquid filling a pipeline is impeded when the gas ahead of it cannot escape. Entrapped gas will lead to a significant pressure build-up in front of the liquid column, which slows down the column and eventually bounces it back. The pressure and temperature in the gas may become dangerously high, and for example, lead to fires and explosions caused by auto-ignition. This paper considers the case where the trapped gas can escape through a vent. One new element is that the pressure head of the liquid supply reservoir is fluctuating instead of staying constant. The obtained analytical and numerical solutions are utilized in parameter variation studies that give deeper insight in the system's behavior.

Dynamic Force on an Elbow Caused by a Traveling Liquid Slug Hou, Darcy Q.; TIJSSELING, Arris S.; Bozkuş, Zafer (ASME International, 2014-06-01) The impact force on an elbow induced by traveling isolated liquid slugs in a horizontal pipeline is studied. A literature review reveals that the force on the elbow is mainly due to momentum transfer in changing the fluid flow direction around the elbow. Therefore, to accurately calculate the magnitude and duration of the impact force, the slug arrival velocity at the elbow needs to be well predicted. The hydrodynamic behavior of the slug passing through the elbow needs to be properly modeled too. A combina...
Modeling Liquid Slugs Accelerating in Inclined Conduits Korzilius, Stan P.; Tijsseling, Arris S.; Bozkuş, Zafer; Anthonissen, Martijn J. H.; Schilders, Wil H. A. (ASME International, 2017-12-01) In this article, we simulate traveling liquid slugs in conduits, as they may occur in systems carrying high-pressure steam. We consider both horizontal and inclined pipes in which the slug is accelerated by a suddenly applied pressure gradient, while at the same time, gravity and friction work in the opposite direction. This causes a steep slug front and an extended slug tail. The shapes of front and tail are of interest since they determine the forces exerted on bends and other obstacles in the piping syst...
Analytical and Numerical Solution for a Rigid Liquid Column Moving in a Pipe with Fluctuating Reservoir Head and Venting Entrapped Gas TİJSSELİNG, Arris S; HOU, Qingzhi; Bozkuş, Zafer (2016-07-21) The motion of liquid filling a pipeline is impeded when the gas ahead of it cannot escape freely. Trapped gas will lead to a significant pressure build-up in front of the liquid column, which slows down the column and eventually bounces it back. This paper is an extension of previous work by the authors in the sense that the trapped gas can escape through a vent. Another addition is that the driving pressure is not kept constant but fluctuating. The obtained analytical and numerical solutions are utilized i...
A New Method for Prediction of the Transient Force Generated by a Liquid Slug Impact on an Elbow of an Initially Voided Line KAYHAN, Bulent A.; Bozkuş, Zafer (ASME International, 2011-04-01) The aim of the present study is to predict the impact force applied by an individual transient liquid slug on an elbow at the end of a horizontal and initially empty pipeline. The liquid slug is driven by pressurized air in a tank located upstream of the pipeline. The time dependent pressure distribution along the elbow and a vertical extension segment after the elbow are solved with a 1D numerical approach along a curved line mesh. An assumed and calibrated axial turbulent velocity profile function with 3D...
Performance Evaluation of Internal Drains of Earthen Dams Çalamak, Melih; Yanmaz, Ali Melih (American Society of Civil Engineers (ASCE), 2018-12-01) Seepage is always expected in earthen dams because they are made of porous materials. However, it should be always under control and its amount and pore-water pressures should be kept below acceptable limits. This can be satisfied by installing internal drains. This study reviews the characteristics of blanket, chimney, and toe drains and assesses their suitability and effectiveness for various material types and geometric characteristics in separate cases. Numerical simulations are conducted for steady-sta...
