Development of a multigrid accelerated euler solver on adaptively refined two- and three-dimensional cartesian grids Çakmak, Mehtap; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2009) Cartesian grids offer a valuable option to simulate aerodynamic flows around complex geometries such as multi-element airfoils, aircrafts, and rockets. Therefore, an adaptively-refined Cartesian grid generator and Euler solver are developed. For the mesh generation part of the algorithm, dynamic data structures are used to determine connectivity information between cells and uniform mesh is created in the domain. Marching squares and cubes algorithms are used to form interfaces of cut and split cells. Geome...
Development of an all speed navier-stokes preconditioner for two and three dimensional flows on hybrid grids Baş, Onur; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2015) In this study, a novel Mach uniform preconditioning method is developed for the solution of Euler/Navier-Stokes equations at subsonic and incompressible flow conditions. In contrast to the methods developed earlier in which the conservation of mass equation is preconditioned, the conservation of energy equation is preconditioned in the present method to enforce the divergence free constraint on the velocity field even at the limiting case of incompressible, zero Mach number flows. The proposed Mach-uniform ...
Development of a two-dimensional euler solver for unstructured grids Sezal, İsmail Hakkı; Aksel, M. Haluk; Department of Mechanical Engineering (2001)
Development of a Navier-Stokes solver for multi-block applications Erdoğan, Erinç; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2004) A computer code is developed using finite volume technique for solving steady twodimensional and axisymmetric compressible Euler and Navier-Stokes equations for internal flows by أmulti-blockؤ technique. For viscous flows, both laminar and turbulent flow properties can be used. Explicit one step second order accurate Lax-Wendroff scheme is used for time integration. Inviscid solutions are verified by comparing the results of test cases of a support project which was supported by ONERA/France for Turkey T-10...
Development of an incompressible navier-stokes solver with alternating cell direction implicit method on structured and unstructured quadrilateral grids Baş, Onur; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2007) In this research, the Alternating Cell Direction Implicit method is used in temporal discretisation of the incompressible Navier-Stokes equations and compared with the well known and widely used Point Gauss Seidel scheme on structured and quadrilateral unstructured meshes. A two dimensional, laminar and incompressible Navier-Stokes solver is developed for this purpose using the artificial compressibility formulation. The developed solver is used to obtain steady-state solutions with implicit time stepping m...
