Experimental and numerical analysis of a dam-break flow through different contraction geometries of the channel
Kocaman, Selahattin; Güzel, Hasan; Evangelista, Stefania; Özmen-Çağatay, Hatice; Viccione, Giacomo (MDPI, 2020)Dam-break wave propagation usually occurs over irregular topography, due for example to natural contraction-expansion of the river bed and to the presence of natural or artificial obstacles. Due to limited available dam-break ... -
Experimental and Numerical Investigation of 3D Dam-Break Wave Propagation in an Enclosed Domain with Dry and Wet Bottom
Kocaman, Selahattin; Evangelista, Stefania; Güzel, Hasan; Dal, Kaan; Yılmaz, Ada; Viccione, Giacomo (MDPI, 2021)Dam-break flood waves represent a severe threat to people and properties located in downstream regions. Although dam failure has been among the main subjects investigated in academia, little effort has been made toward ... -
Experimental and Numerical Investigation of Shock Wave Propagation Due to Dam-Break Over a Wet Channel
Turhan, Evren; Özmen-Çağatay, Hatice; Kocaman, Selahattin (HARD Publishing Company, 2019)We investigated the propagation of shock waves in a prismatic rectangular channel with a horizontal wet bed. Saltwater was used as a Newtonian fluid within the entire channel instead of normal water for representing the ... -
An experimental investigation of dam-break induced flood waves for different density fluids
Özmen-Çağatay, Hatice; Turhan, Evren; Kocaman, Selahattin (Elsevier, 2022)The present study aims to investigate the effect of various fluids on dam-break flow propagation in a rectangular and horizontal channel under dry bed conditions. Laboratory experiments were carried out to produce dam break ... -
A multi-parameter calibration method for the numerical simulation of morphodynamic problems
Evangelista, Stefania; Giovinco, Gaspare; Kocaman, Selahattin (De Gruyter Open Ltd, 2017)Calibration of parameters of mathematical models is still a tough task in several engineering problems. Many of the models adopted for the numerical simulations of real phenomena, in fact, are of empirical derivation. ... -
Numerical analysis of hydroelasticity problems by coupling WCSPH with multibody dynamics
Yılmaz, Ada; Kocaman, Selahattin; Demirci, Mustafa (Elsevier, 2022)This paper aims to extend the implementation of DualSPHysics-Project Chrono coupling to hydroelasticity problems involving free-surface flows and deformable elastic boundaries. In the present model, the fluid sub-domain ... -
Numerical modeling of the dam-break wave impact on elastic sluice gate: A new benchmark case for hydroelasticity problems
Yılmaz, Ada; Kocaman, Selahattin; Demirci, Mustafa (Elsevier, 2021)This paper presents a newly-designed experimental setup based on the interaction of a dam-break flow with an elastic sluice gate in the context of the hydroelasticity problems. As the experimental measurement, displacements ... -
A Numerical Validation of 3D Experimental Dam-Break Wave Interaction with a Sharp Obstacle Using DualSPHysics
Capasso, Salvatore; Tagliafierro, Bonaventura; Güzel, Hasan; Yılmaz, Ada; Dal, Kaan; Kocaman, Selahattin; Viccione, Giacomo; Evangelista, Stefania (MDPI, 2021)The presence downstream of a dam of either rigid or erodible obstacles may strongly affect the flood wave propagation, and this complex interaction may lead to further dramatic consequences on people and structures. The ...
