One of the aims of the study, is to develop a numerical analysis tool for thermochemical ablation problem under hypersonic flow conditions. The other aim is to include the effects of the graphite ablation to a design optimization tool which uses adjoint method. In this study, IRV2 geometry is selected as the original geometry and optimization study is performed under reacting flow conditions. Drag coefficient of the geometry is reduced without increasing the stagnation point temperature. After the optimization study, ablation behavior of the original geometry and the optimized geometry have been analyzed and compared.

Aerothermodynamic shape optimization of hypersonic blunt bodies Eyi, Sinan (2015-07-03) The aim of this study is to develop a reliable and efficient design tool that can be used in hypersonic flows. The flow analysis is based on the axisymmetric Euler/Navier-Stokes and finite-rate chemical reaction equations. The equations are coupled simultaneously and solved implicitly using Newton's method. The Jacobian matrix is evaluated analytically. A gradient-based numerical optimization is used. The adjoint method is utilized for sensitivity calculations. The objective of the design is to generate a h...
LOOSE COUPLING OF SU2 MULTIPHYSICS CODE WITH PATO TO ANALYZE THE SURFACE RECESSION EFFECT ON SURFACE HEAT FLUX Çelik, Mutlu; Uğur, Ömür; Eyi, Sinan; Department of Scientific Computing (2022-12-30) In this thesis, open source softwares SU2 Multiphysics and The Porous material Analysis Toolbox (PATO) based on OpenFOAM are used to conduct loosely coupled analysis of hypersonic non-equilibrium flow and thermochemical ablation. Both solvers have become prominent open source softwares with numerous validation and verification cases. NEMO, the non-equilibrium modeling solver of SU2 is used to model chemically reactive and non-equilibrium flows by integrating thermochemistry library of Mutation++. SU2-NEMO s...
Ablation modeling for high speed internal and external flows Onay, Oğuz Kaan; Eyi, Sinan; Department of Aerospace Engineering (2020) In this thesis study, the ablation of graphitic materials is modeled and two different analysis tools are developed. In the first model, the computations are conducted with a decoupled approach. Secondly, a more generalized calculation method is introduced via coupling the flow field and solid conduction analysis codes. In the modeling studies, both the gas and solid domains are assumed to be axisymmetric and the physical domains are discretized with structured finite volume cells. For the flow field analys...
Design optimization of rocket nozzles in chemically reacting flows Yumusak, M.; Eyi, Sinan (2012-07-30) The objective of this study is to develop a reliable and efficient design tool that can be used in chemically reacting flows. The flow analysis is based on the axisymmetric Euler and the finite rate chemical reaction equations. The finite rate chemistry model includes eight species and eleven reaction equations. These coupled equations are solved by using Newton's method. Both the numerical and the analytical methods are used to calculate the Jacobian matrices. Sensitivities are evaluated by using the adjoi...
Experimental investigation on sharp-crested rectangular weirs Gharahjeh, Siamak; Aydın, İsmail; Altan Sakarya, Ayşe Burcu; Department of Civil Engineering (2012) This study is an experimental research to formulate the discharge over sharp-crested rectangular weirs. Firstly, a series of measurements on different weir heights were conducted to find the minimum weir height for which channel bed friction has no effect on discharge capacity. After determining the appropriate weir height, weir width was reduced to collect data on discharge-water head over weir relationship for a variety of different weir openings. Then, the data was analyzed through regression analysis al...
