Experiences with two detached eddy simulation approaches through use of a high-order finite volume solver Cengiz, Kenan; Özyörük, Yusuf (Wiley, 2020-08-01) In the present study, two advanced detached eddy simulation (DES) approaches, shear-layer-adapted delayed DES and zonal DES in mode II, which are known to help transition from RANS to LES mode, are employed in various flow...
Main Rotor - Tail Rotor Interactional Noise Atalay, Mehmet Melih; Şenipek, Murat; Yücekayalı, Arda; Özyörük, Yusuf (2019-10-30) In this paper, effects of main rotor – tail rotor interactions on noise characteristics are investigated for a typical 10 ton class helicopter. Evaluations are performed at hover and quartering flight conditions with top-f...
Aerodynamic Performance Analyses of Iced Wind Turbine Blade Profile with Transitional DDES Yalçın, Özgür; Yırtıcı, Özcan; Özyörük, Yusuf; Tuncer, İsmail Hakkı (null; 2019-09-20)
Comprehensive Rotorcraft Aeroacoustics: Investigation of Surface Pressure Distribution Methods for Rotor Noise Şenipek, Murat; Yücekayalı, Arda; Ortakaya, Yüksel; Özyörük, Yusuf (2019-09-20)
Investigation of Air Core Characteristics of a Pressure Swirl Injector Using Two Different Volume of Fluid Methods Öztürkmen, Musa Onur; Özyörük, Yusuf (null; 2019-09-20)
Boundary Layer Transition Prediction over Wind Turbine Blade Profile through Detached Eddy Simulation Yalçın, Özgür; Özyörük, Yusuf (null; 2019-05-14) This proposed study aims at simulating slightly separated flow over the NREL S826 wind turbine blade profile with delayed detached-eddy simulation (DDES) strategy. The Reynolds number is relatively low and the angles of at...
Flow and Noise Prediction of Doors-on M219 Cavity through Improved Delayed Detached Eddy Simulations Coşkun, Seyfettin; Özyörük, Yusuf (2019-05-14) High survivability and low observability requirements of modern fighter airplanes necessitate internal carriage of the stores. During their deployment the doors of internal weapon bays are opened transitionally, forming a ...
Fully transient conjugate analysis of silica-phenolic charing ablation coupled with interior ballistics Alanyalıoğlu, Çetin Ozan; Özyörük, Yusuf (2019-01-01) © 2019, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.Due to its excellent insulation capability, usage of silica-phenolic charring ablator as nozzle liner is a common practice in solid ...
Three dimensional axisymmetric sound propagation through a duct with aerosol Arslan, Ersen; Çalışkan, Mehmet; Özyörük, Yusuf (Elsevier BV, 2018-11-10) The aim of this study is to develop solutions for the propagation of spinning sound waves in air-filled circular ducts containing water droplets (regarded as an aerosol). There exist several theoretical approaches in liter...
High-order detached eddy simulation of unsteady flow around NREL S826 airfoil Yalçın, Özgür; Cengiz, Kenan; Özyörük, Yusuf (Elsevier BV, 2018-08-01) Delayed detached eddy simulation (DDES) has been a common approach for unsteady turbulent flow problems, but it has several weaknesses which limit its use to detached flows. On the other hand, some enhancements introduced ...
