Liquid slugs have a relatively low mass and can therefore when they occupy a full cross-section of a pipeline be accelerated to very high velocities by means of pressurized gas. When entrapped gas pockets are present, pressures and temperatures may become dangerously high. Simple models and analytical solutions are derived and used to predict transient velocities, pressures and temperatures. The models have a generic character as they also describe the basics of breaking surface waves impacting on a wall, and pigs and bullets propelled by compressed gas.

ANALYTICAL EXPRESSIONS FOR LIQUID-COLUMN VELOCITIES IN PIPELINES WITH ENTRAPPED GAS Tijsseling, Arris S.; Hou, Qingzhi; Bozkuş, Zafer (2015-01-01) High pressures and high temperatures may arise in pipelines when a liquid column is suddenly accelerated into a gas pocket trapped at a closed end. A mass oscillation occurs that is described by nonlinear equations for both liquid and gas. Analytical expressions are derived for the uniform velocity of the liquid column, from which pressures and gas temperatures follow. The obtained results are validated against theoretical and experimental results published by fellow researchers.
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...
Boş Bir Boru Sisteminde Değişken Akımlı Bir Su Kütlesinin Paketinin Hidrodinamiği Bozkuş, Zafer (1995-01-01) Liquid slugs (water pockets) are propelled into an empty pipe under various driving pressures; the pipe's extension ends at an elbow whereon the slugs impact and disintegrate. Dynamic pressures recorded at various locations along the system indicate the complex and somewhat random structure of the transient. High-speed movies of the evolving slug just prior to impact show that significant air entrainment and breakup of the slug occurs. A simplified analytical model is developed to predict the slug dynamics;...
Investigation of gas seepages in Thessaloniki mud volcano in the Mediterranean Sea MEREY, ŞÜKRÜ; Longinos, Sotirios Nik (2018-09-01) Gas seepages are commonly observed in marine environment. Especially, gas seepages due to anthropogenic gas hydrate dissociation are big concerns recently. In the Eastern Mediterranean Sea, Thessaloniki mud volcano was detected. Gas hydrate stability conditions in this mud volcano is very fragile. For this reason, in this study, gas seepages were predicted by using HydrateResSim at different seafloor temperature increments varying from 1 to 5 degrees C and different sediment permeability values varying from...
Experimental analysis on the measurement of ballistic properties of solid propellants Cuerdaneli, S.; Ak, M. A.; Ulaş, Abdullah (2007-06-16) Ballistic properties of solid propellants play an important role in the performance of the solid propellant rocket motors. Therefore, ballistic properties of a likely propellant should be known and provided to the design engineers. In this study, a specific AP/HTPB composite solid propellant (SCP) was examined to obtain steady-state linear burning rates as a function of pressure and propellant initial temperature, temperature sensitivity, and pressure deflagration limit (PDL). In some tests micro-thermocoup...
