Bu çalışmada hipersonik akışlar için kullanılabilecek isabetli ve etkin bir hesaplamalı akışkanlar dinamiği kodu geliştirilmesi amaçlanmaktadır. Akış analizi üç boyutlu Navier-Stokes denklemlerini temel almaktadır. Bu denklemler Newton metoduyla çözülmekte ve Jacobian matrislerini hesaplamak için analitik metot kullanılmaktadır. Model olarak alınan AS-202 Apollo uzay aracı geometrisi üzerinde akış parametreleri ve taşınımla ısı transferi analiz edilecektir. Ayrıca nümerik olarak stabil olan ve genelde hipersonik akış uygulamalarında iyi tahminler sağlayan Spalart-Allmaras türbülans modeli kullanılarak hipersonik akış için türbülanslı akış analizi yapılacaktır.

Three dimensional hypersonic flow analysis around a reentry vehicle using navier‐stokes equations Özgün, Muharrem; Eyi, Sinan (null; 2016-07-11) The purpose of this study is to develop an accurate and efficient CFD code that can be used in hypersonic flows. The flow analysis is based on the three dimensional Navier-Stokes equations. These equations are solved by using Newton/Newton-Gmres method. The analytical method is used to calculate the Jacobian matrix. Flow parameters and convective heat transfer are analyzed on Apollo AS-202 Command Module. Also, algebraic Baldwin-Lomax turbulence model and one-equation Spalart-Allmaras turbulence model is us...
Improving flow structure and natural convection within fin spacings of plate fin heat sinks Özet, Mehmet Erdem; Tarı, İlker; Department of Mechanical Engineering (2015) The main objectives of this thesis are to numerically investigate the previously observed recirculation zones and longitudinal vortices that occur in low fin height plate finned horizontal heat sinks and to improve the flow structures and heat transfer in these zones using various approaches with the help of simulations performed using commercially available CFD software. The approaches used for improvements are replacing the outer most fins with higher ones, introducing gaps on the length of the fins in va...
Design and performance analysis of double-flux supersonic air ejector Bozkır, Berk; Alemdaroğlu, Hüseyin Nafiz; Department of Aerospace Engineering (2018) The main purpose of this study is to design a double-flux supersonic ejector and to evaluate its performance associated with its entrainment ratio by employing Computational Fluid Dynamics methods as well as one-dimensional approach. Since the performance of the ejector systems is strongly dependent on the design, this study concentrates on maximizing the entrainment ratio by varying the corresponding angles and the lengths of the critical segments such as mixing angle, divergence angle, mixing throat lengt...
Implementation and comparison of turbulence models on a flat plate problem using a Navier-Stokes solver Genç, Balkan Ziya; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2003) For turbulent flow calculations, some of the well-known turbulence models in the literature are applied on a previously developed Navier-Stokes solver designed to handle laminar flows. A finite volume formulation, which is cell-based for inviscid terms and cell-vertex for viscous terms, is used for numerical discretization of the Navier-Stokes equations in conservative form. This formulation is combined with one-step, explicit time marching Lax-Wendroff numerical scheme that is second order accurate in spac...
