Book Implicit Algorithm for Numerical Solution of the Laminar Incompressible Two Dimensional Navier Stokes Equations

Download or read book Implicit Algorithm for Numerical Solution of the Laminar Incompressible Two Dimensional Navier Stokes Equations written by D. P. Rizzetta and published by . This book was released on 1988 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical procedure is presented for solution of the laminar incompressible two dimensional Navier Stokes equations written in terms of the stream function and vorticity. The full implicit unified method is capable of treating both steady and unsteady flows. The governing equations are solved in conservation form, incorporating a general transformation of the independent variables so that arbitrary geometrical configurations may be considered. In the steady case, the algorithm corresponds identically to Newton's method as applied to the solution of nonlinear partial differential equations. For unsteady flows, the procedure is second order accurate temporally as well as spatially. An analysis of a model system of equations is provided which indicates numerical stability. Utility of the method is verified by calculation of representative examples of both steady and unsteady flow fields. These include the classic driven cavity problem and the unsteady flow about a circular cylinder. Results of these computations are compared with previous numerical solutions as well as with experimental data. Keywords; Navier Stokes equations; Computational fluid dynamics; Newton's method.

Book Templates for the Solution of Linear Systems

Download or read book Templates for the Solution of Linear Systems written by Richard Barrett and published by SIAM. This book was released on 1994-01-01 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, which focuses on the use of iterative methods for solving large sparse systems of linear equations, templates are introduced to meet the needs of both the traditional user and the high-performance specialist. Templates, a description of a general algorithm rather than the executable object or source code more commonly found in a conventional software library, offer whatever degree of customization the user may desire. Templates offer three distinct advantages: they are general and reusable; they are not language specific; and they exploit the expertise of both the numerical analyst, who creates a template reflecting in-depth knowledge of a specific numerical technique, and the computational scientist, who then provides "value-added" capability to the general template description, customizing it for specific needs. For each template that is presented, the authors provide: a mathematical description of the flow of algorithm; discussion of convergence and stopping criteria to use in the iteration; suggestions for applying a method to special matrix types; advice for tuning the template; tips on parallel implementations; and hints as to when and why a method is useful.

Book A New Method for the Solution of the Incompressible Navier Stokes Equations

Download or read book A New Method for the Solution of the Incompressible Navier Stokes Equations written by Hazem Said and published by . This book was released on 2001 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical Solution of the incompressible Navier-Stokes (INS) equations in primitive variables requires special care to ensure that the resulting flow field will satisfy the discrete governing equations (DGE). However, these equations are not satisfied by the existing solution methods, thus requiring the need to develop a new method. A new method is developed in this work to solve the INS equations in primitive variables. The method uses the velocity and pressure gradients as dependent variables compared to velocity and pressure that are used by all other primitive variables methods. These new dependent variables require additional constraint to be determined. The condition of irrotationality of the gradient of the pressure is employed to give the necessary equations to close the problem. Thus the flow field is represented by a new set of equations that when solved together produces a solution that satisfies the DGE. of the present method are summarized as follows: (1) it eliminates the compatability condition of the pressure equation typical of all pressure-based techniques, (2) it satisfies the discrete continuity and momentum equations. (3) Boundary conditions are physically known for all the dependent variables. (4) It eliminates the inversion of the implicit operator typical of the implicit primitive variables formulation, (5) Robust, stable and more accurate computational codes can be developed. Numerical results are obtained for the driven cavity problem, using both the explicit and the implicit forms of the method. Results are obtained for Reynolds numbers of 100, 400 and 1000. These results show that the present method produces a stable solution and that the resulting flow field does satisfy the DGE to machine zero.

Book Computational Fluid Dynamics

Download or read book Computational Fluid Dynamics written by Jiri Blazek and published by Elsevier. This book was released on 2005-12-20 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational Fluid Dynamics (CFD) is an important design tool in engineering and also a substantial research tool in various physical sciences as well as in biology. The objective of this book is to provide university students with a solid foundation for understanding the numerical methods employed in today’s CFD and to familiarise them with modern CFD codes by hands-on experience. It is also intended for engineers and scientists starting to work in the field of CFD or for those who apply CFD codes. Due to the detailed index, the text can serve as a reference handbook too. Each chapter includes an extensive bibliography, which provides an excellent basis for further studies.
