In this study, an algorithm for the solution of chemically reacting flows in a channel reactor is developed by using boundary layer equations. The governing flow equations are simplified under certain assumptions with the application of similarity transformation. As a consequence of simplification, the characteristics of flow equations are changed to parabolic partial differential equations (PDE). Parabolic PDEs can be solved by numerical techniques initially designed for ordinary differential equations (ODE), such as a method of lines. The spatial terms of the equation set are discretized by the finite difference method. The resulting set of boundary layer equations is written in differential algebraic form. The set of equations is solved as a marching problem in the 2D domain with given initial and boundary conditions using MATLAB ode15i solver. The developed algorithm is used to investigate the formation of a flame in a reacting channel flow and the parameters affecting flame development.

Pressure-velocity coupling algorithm-based pressure reconstruction from PIV for laminar flows Gunaydinoglu, Erkan; Kurtuluş, Dilek Funda (Springer Science and Business Media LLC, 2020-01-01) In this study, we propose a method to reconstruct pressure fields from planar particle image velocimetry measurements for laminar flows by employing semi-implicit method for pressure-linked equations algorithm to solve governing equations where measured velocities are inherently used as boundary conditions. The method starts with interpolating the measured velocity field on a staggered computational grid. The continuity equation, in the form of pressure equation for incompressible flows, is solved with this...
Numerical Analysis of One-Dimensional Sound Propagation Through a Duct Containing Water Droplets Arslan, Ersen; Özyörük, Yusuf; Çalışkan, Mehmet (2017-03-01) In this paper sound propagation through an air-filled circular duct containing water droplets has been studied by solving numerically one-dimensional linearized Euler equations in frequency domain. Interactions between the liquid and gas phases were accounted for by proper source terms. Waves were introduced into the domain via Perfectly Matched Layers (PML) equations applied in finite regions adjacent to the truncated ends of the duct. Absorption and dispersion results due to energy transfer from air to th...
NUMERICAL STABILITY OF RBF APPROXIMATION FOR UNSTEADY MHD FLOW EQUATIONS Gurbuz, Merve; Tezer, Münevver (2019-01-01) In this study, the radial basis function (RBF) approximation is applied for solving the unsteady fluid flow and magnetohydrodynamic (MHD) convection flow problems with the use of explicit Euler time discretization and relaxation parameters to accelerate the convergence. The stability analysis is also carried out in terms of the spectral radius of related RBF discretized coefficient matrices. The optimal choices of the time increment, relaxation parameters and physical problem parameters are found for achiev...
Least squares differential quadrature time integration scheme in the dual reciprocity boundary element method solution of convection-diffusion problems Bozkaya, Canan (2005-03-18) The least squares differential quadrature method (DQM) is used for solving the ordinary differential equations in time, obtained from the application of the dual reciprocity boundary element method (DRBEM) for the spatial partial derivatives in convection-diffusion type problems. The DRBEM enables us to use the fundamental solution of the Laplace equation which is easy to implement computationally. The time derivative and the convection terms are considered as the nonhomogeneity in the equation which are ap...
Computation of multi-passage cascade flows with overset and deforming grids Tuncer, İsmail Hakkı (null; 1997-12-01) An overset grid method is applied to the solution of single and multi-passage cascade flows with a compressible Navier-Stokes solver. C-type grids around individual blades are overset onto a Cartesian background grid. Overset grids are allowed to move in time relative to each other as prescribed by the oscillatory plunging motion. The overset grid method uses a simple, robust numerical algorithm to localize moving boundary points and to interpolate solution variables across intergrid boundaries. Computation...
