Rapid Liquid Filling of a Pipe With Venting Entrapped Gas: Analytical and Numerical Solutions
Tijsseling, Arris S.; Hou, Qingzhi; Bozkuş, Zafer (ASME International, 2019-08-01)
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 eventuall...
Fully Coupled Smoothed Particle Hydrodynamics-Finite Element Method Approach for Fluid-Structure Interaction Problems With Large Deflections
Dincer, A. Ersin; Demir, Abdullah; Bozkuş, Zafer; Tijsseling, Arris S. (ASME International, 2019-08-01)
In this study, a combination of the smoothed particle hydrodynamics (SPH) and finite element method (FEM) solving the complex problem of interaction between fluid with free surface and an elastic structure is studied. A br...
Dancing Manhole Cover:A Nonlinear Spring-Mass System
Tijsseling, Arris S; Vasconcelos, Jose G; Hou, Qingzhi; Bozkuş, Zafer (2019-07-19)
Dancing manhole covers are an intriguing and curious phenomenon but extremely dangerous for road vehicles as well as pedestrians. They are reported worldwide after heavy rainfall in urban environment. Stormwater systems ar...
Numerical and experimental investigation of damping in a dam-break problem with fluid-structure interaction
Demir, Abdullah; Dincer, Ali Ersin; Bozkuş, Zafer; Tijsseling, Arris S. (Zhejiang University Press, 2019-04-01)
There have been few experimental and numerical studies on damping effects in fluid-structure interaction (FSI) problems. Therefore, a comprehensive experimental study was conducted to investigate such effects. In experimen...
Effect of Pier Inclination Angle on Local Scour Depth Around Bridge Pier Groups
Bozkuş, Zafer; OZALP, Murat Can; DINCER, A. Ersin (2018-10-01)
The primary objective of this study is to investigate experimentally local scours around bridge pier groups at various inclination angles of piers and also to develop empirical local scour depth equations. In the study, tw...
Optimization of Pipe Irrigation Networks
MARIM, Gokhan; Darama, Yakup; Bozkuş, Zafer (2018-09-01)
Pipe irrigation networks are the most important systems regarding a country's agricultural production and water conservation efforts. Today, irrigation for agriculture is the sector that leads to highest water consumption....
Prediction of Pressure Variation at an Elbow Subsequent to a Liquid Slug Impact by Using Smoothed Particle Hydrodynamics
DİNÇER, Ali Ersin; Bozkuş, Zafer; TIJSSELING, A. S. (2018-06-01)
Liquid slug flow driven by pressurized air in an inclined pipe with a downstream elbow is investigated numerically. As the liquid slug hits the elbow, the impact pressure and the associated force generated at the elbow may...
Moving liquid column with entrapped gas pocket and fluid-structure interaction at a pipe's dead end: A nonlinear spring-mass system
Tijsseling, Arris S; Hou, Qingzhi; Bozkuş, Zafer (2018-01-01)
Moving liquid columns and entrapped gas pockets are basic ingredients in the industrial processes of starting flow and pipe filling. Within limits, the liquid columns can be modeled as masses and the gas pockets as springs...
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 appl...
Analytical Solutions for Liquid Slugs and Pigs Traveling in Pipelines with Entrapped Gas
TİJSSELİNG, Arris S; QİNGZHİ, Hou; Bozkuş, Zafer (2017-07-20)
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, pres...
