HIGH-FIDELITY NUMERICAL INVESTIGATION OF A HIGH PRESSURE TURBINE COOLED VANE Gokenis, Furkan; Peneklioglu, Kagan; Oksuz, Ozhan; Erdem, Erinc; Eyi, Sinan (2024-01-01) A significant portion of a turbine blade/vane might experience a transitional boundary layer presumably on the suction surface, which affects the rate of heat transfer. Appropriate choice of the turbulence model on predict...
Numerical Modeling of Hypersonic Air and Carbon Dioxide Flows in Thermochemical Non-Equilibrium with SU2-NEMO Solver Çelik, Mutlu; Uğur, Ömür; Eyi, Sinan (2022-06-23) Modeling of hypersonic aerothermodynamics in non-equilibrium flow is a challenging problem of aircraft design. Especially, prediction of atmospheric reentry and other planet’s entry heat loads are significant for aerospace...
Diffusion in Hypersonic Flows Gür, Hilmi Berk; Eyi, Sinan (Nova Science Pub Inc, 2020-10-01) In hypersonic flows, air goes into chemical reaction due to high temperature. Therefore, in addition to the Navier-Stokes Equations, chemical reaction equations need to be solved to analyze hypersonic flows. A model may be...
Computational modelling and analysis of porous bleed holes at supersonic speeds Akar, Gökhan; Eyi, Sinan (2020-01-01) © 2020, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.Shock Wave / Boundary Layer Interaction is an important issue that should be taken into account when studying inlet design. Bleed ho...
Comparison of Fully Coupled and DecoupledModeling Results of Graphite Ablation In Hypersonic Flows Onay, Oğuz; Eyi, Sinan (2019-09-20) A thermochemical ablation modeling tool is developed for graphite material in air for reactive hypersonic flows. Multi-species and axisymmetric Navier-Stokes equations are solved for the flow field analysis. Arrhennius typ...
Integrated Shap Optimization of RAE-M2129 Inlet for Aerodynamic Performance and Reduced Radar Cross Section Unlu, T; Atasoy, M; Dincer, E; Eyi, Sinan (null; 2019-09-20) Low observability is a key quality of air breathing military aircrafts and the forward observability of such aircrafts are mostly determined by the open ended cavities formed by the air intakes. Geometrical shape of an S-d...
Aerothermodynamic Design Optimization of Hypersonic Vehicles Eyi, Sinan; Boyd, Iain D. (American Institute of Aeronautics and Astronautics (AIAA), 2019-04-01) The objective of this study is to develop a reliable and efficient design optimization method for hypersonic vehicles focused on aerothermodynamic environments. Considering the nature of hypersonic flight, a high-fidelity ...
Shape Optimization of Reentry Vehicles to Minimize Heat Loading Eyi, Sinan; Boyd, I D (2019-01-06) The objective of the current study is to design an optimum reentry vehicle shape that minimizes heat loading subject to constraints on the maximum values of surface heat flux and temperature. A new heat loading formulation...
Reacting flow analysis of a cavity-based scramjet combustor using a Jacobian-free Newton-Krylov method Rouzbar, R.; Eyi, Sinan (Cambridge University Press (CUP), 2018-12-01) The scramjet is a rather a new technology and there are many issues related to their operation, especially when it comes to the combustion processes. Combustion in high-speed flows causes various problems such as flame ins...
