Download Augmented Stabilized Formulations with Fictitious Boundary Methods Book in PDF, Epub and Kindle
Augmentation of the SUPS formulation was introduced earlier and successfully applied to solving incompressible Navier- Stokes equations for both two dimensional and three dimensional problems. Fictitious boundary methods (FBM) is a new methodology that aid the study of flow descriptions around solid obstacles on fixed Cartesian product grids that do not require body confirming meshes. FBM has been applied to lower order finite element and spectral/hp least squares techniques. We test the augmented stabilized finite element formulation introduced earlier, (ASUPS) to the fictitious boundary context and use it to solve incompressible flow problems. Utilizing the advantages of fictitious boundary methods we present solutions to flow around an array of two dimensional and three dimensional problems. In two dimensional flow computations we solve flow past a circular and elliptical shaped cylinders. For the ellipse shaped obstacles in a Newtonian flow field we examine the effects of varying boundary conditions and aspect ratios on the flow metrics. Finally we extend the procedures to solving two ellipse and two circular shaped obstacles facing the free stream. In three dimensional computations we examine incompressible flow around a three dimensional ellipse shaped obstacle at Reynolds number Re-200.

Download Finite Element Methods for Incompressible Flow Problems Book in PDF, Epub and Kindle
This book explores finite element methods for incompressible flow problems: Stokes equations, stationary Navier-Stokes equations and time-dependent Navier-Stokes equations. It focuses on numerical analysis, but also discusses the practical use of these methods and includes numerical illustrations. It also provides a comprehensive overview of analytical results for turbulence models. The proofs are presented step by step, allowing readers to more easily understand the analytical techniques.

Download Adaptive Incompressible Flow Computations with Linearly Implicit Time Discretization and Stabilized Finite Elements Book in PDF, Epub and Kindle
Abstract: "Fully adaptive solutions of incompressible flow problems employing the discretization sequence first in time then in space are presented. The time discretization is done by linearly implicit one-step methods possibly of high order with automatic step size control. A posteriori error estimates for the stabilized finite element discretization in space are obtained by solving local Dirichlet problems with higher accuracy. Once those estimates have been computed, we are able to control time and space grids with respect to required tolerances and necessary computational work. The devised method is applied to two benchmark problems in 2D."
