Effect Of Inlet Velocity Profıle And Entrance Length On Abdominal Aortic Aneurysm Hemodynamics Simulations Ramazanlı, Burcu; Sert, Cüneyt; Yavuz, Mehmet Metin (2023-01-01) In computational Abdominal Aortic Aneurysm (AAA) hemodynamics studies, along with adjusting the problem geometry, mesh, transport, turbulence and rheology models; setting up boundary conditions (BC) is also a very importan...
Simulation of turbulence induced sound generation inside stenosed femoral artery models with different severities and eccentricities Ozden, Kamil; Yazıcıoğlu, Yiğit; Sert, Cüneyt (2021-09-01) Background and objectives: Recent developments of low-cost, compact acoustic sensors, advanced signal processing tools and powerful computational resources allow researchers design new scoring systems for acoustic detectio...
Effect of stenosis shape on the sound emitted from a constricted blood vessel Ozden, Kamil; Sert, Cüneyt; Yazıcıoğlu, Yiğit (Springer Science and Business Media LLC, 2020-03-01) Effect of stenosis shape on the post-stenotic pressure fluctuations and the sound emitted from a constricted blood vessel is studied numerically. Large eddy simulations are performed using OpenFOAM under pulsatile flow con...
Numerical investigation of wall pressure fluctuations downstream of concentric and eccentric blunt stenosis models Ozden, Kamil; Sert, Cüneyt; Yazıcıoğlu, Yiğit (SAGE Publications, 2020-01-01) Pressure fluctuations that cause acoustic radiation from vessel models with concentric and eccentric blunt stenoses are investigated. Large eddy simulations of non-pulsatile flow condition are performed using OpenFOAM. Cal...
Optimization of Joule-Thomson cryocooler heat exchanger using one-dimensional numerical modeling Baki, Murat; Okutucu-Özyurt, Tuba; Sert, Cüneyt (Elsevier BV, 2019-12-01) Steady state operation of the heat exchanger of a Joule-Thomson cryocooler is studied numerically through a one-dimensional model. Argon is used as the working fluid. The developed model is first verified using a cooler co...
Simulation of Laminar Flow inside Microchannels with Realistic Surface Roughness Akbaş, Batuhan; Sert, Cüneyt (2019-08-01) Flows inside microchannels have been studied both experimentally and numerically for many years, but still there are debatable points. The critical question that needs to be answered is whether the friction factor and t...
Development of a Material Response Solver for Charring Ablative Materials Coşkun, Volkan; Sert, Cüneyt; Acar, Bülent (2019-06-14) Development of a solver in order to estimate the material response of charring ablative materials which are utilized as thermal protection systems in space vehicles is presented. First, the governing equations for model...
Large Eddy Simulation of Blood Flow Inside Vessels for Acoustic Diagnosis of Atherosclerosis Sert, Cüneyt; Yazıcıoğlu, Yiğit (2018-10-20) Atherosclerosis is a cardiovascular disease, in which plaque builds up inside a blood vessel, narrowing it down and forming a stenosis that adversely affects flow. Because of the constriction, turbulent flow occurs at the ...
Use of artificial neural networks for the prediction of time-dependent air speed variation in metro stations KOC, Gencer; Sert, Cüneyt; Albayrak, Kahraman (2018-09-01) In this study, the time-dependent, induced air speeds at critical sections of underground metro stations are assessed using a novel one-dimensional data-driven approach. For this purpose, three artificial neural networks a...
Simplified Numerical Approach for the Prediction of Aerodynamic Forces on Grid Fins DIKBAS, Erdem; Baran, Özgür Uğraş; Sert, Cüneyt (2018-07-01) Grid fins are unconventional control devices used for aerodynamic control of various types of missiles. Low hinge moment requirement and superior packaging potential make grid fins attractive alternatives to conventional p...
