Cartesian grids constitute a special branch in unstructured grid technology. They use specially designed algorithms to generate automatic grids for complex geometries and to simulate flows around such geometries regardless of the body shape and number of bodies. Cartesian grids are generated by constructing a quadtree based data structure for the purpose of connecting the Cartesian cells to each other. A “hands-off”, Cartesian grid generator based Euler solution called GeULER is implemented in object-oriented FORTRAN programming language. In this study, implementations of generated two-dimensional adaptive refinement/coarsening scheme codesare appended to the developed compressible flow solver by using special Cartesian-based algorithms, namely cut-cell adaptation and curvature adaptation around BOEING TR-1322 multi-element airfoil. A subsonic flow at free stream Mach number of 0.11 around the airfoil is tested to predict pressure distributions around it and Mach contours of the flow are depicted by using the developed GeULER code.

Kartezyen ağlar yapısal olmayan ağ teknolojisi içinde özel bir dal oluşturmaktadır. Karmaşık geometriler için otomatik ağ oluşturmak ve bu gibi geometriler etrafında akışın gövde şeklinden ve sayısından bağımsız şekilde benzetim kurmak için özellikle tasarlanmış algoritmalar kullanırlar. Kartezyen ağlar, Kartezyen hücrelerinin birbirlerine bağlanmalarını sağlamak için oluşturulan dörtlü ağaç temelli veri yapısı kullanarak üretilmiştir. GeULER isimli, kullanıcı müdahalesine gerek olmayan, nesne tabanlı FORTRAN programlama dilinde Kartezyen ağ üreticisi temelli Euler çözümü uygulanmıştır. Bu çalışmada, geliştirilen sıkıştırılabilir akış çözücüsüne, BOEING TR-1322 çoklu-elemanlı kanat profili çevresinde kesik hücre uyarlaması ve eğri uyarlaması gibi özel Kartezyen temelli algoritmalar kullanılarak iki-boyutlu uyarlanabilir geliştirme/genişleme şema kodları ilave edilmiştir. Kanat profili üzerinde, 0.11 serbest akım Mach sayısında, ses altı akışta kanat çevresindeki basınç dağılımının tahmini için test edilmiş ve geliştirilen GeULER kodu kullanılarak akışın Mach konturları tasvir edilmiştir
