Dolejsi, V. (author), Hozman, J. (author)We deal with a numerical solution of the compressible Navier-Stokes equations with the aid of higher order schemes. We employ a combination of the discontinuous Galerkin finite element method for the space semi-discretization and a backward difference formula for the time discretization. Moreover, using a linearization of inviscid as well as...conference paper 2006

Tabata, M. (author)We present energy stable finite element schemes for two-fluid problems with interfacial tension. The interface is captured by solving numerically ordinary differential equations and the interface tension is brought in into the weak formulation of the finite element scheme. Some numerical results of rising bubble problems show the robustness and...conference paper 2006

Gastaldo, L. (author), Babik, F. (author), Herbin, R. (author), Latché, J.C. (author)We present in this paper a pressure correction scheme for barotropic com- pressible Navier-Stokes equations, which enjoys an unconditional stability property, in the sense that the energy and maximum-principle-based a priori estimates of the continuous problem also hold for the discrete solution. The stability proof is based on two independent...conference paper 2006

Ganesan, S. (author), Tobiska, L. (author)This work is devoted to the accurate simulation of incompressible two phase flows. The core of our methodology is the use of interface resolving meshes and the arbitrary Lagrangian-Eulerian (ALE) description of the fluid kinematics. Our numerical scheme is based on second order finite elements, a fractional step ? time discretisation, and a...conference paper 2006

Bassi, F. (author), Crivellini, A. (author)Discontinuous Galerkin (DG) methods have proved to be very well suited for the construction of robust high-order numerical schemes on unstructured and possibly non conforming grids for a wide variety of problems. In this paper we consider natural convection flow problems and present a high-order DG method for their numerical solution. The...conference paper 2006

Lube, G. (author)The numerical solution of the nonstationary, incompressible Navier-Stokes model can be split into linearized auxiliary problems of Oseen type. We present in a unique way different stabilization techniques of finite element schemes on isotropic and hybrid meshes. First we describe the state-of-the-art for the classical residual-based SUPG/PSPG...conference paper 2006

John, V. (author), Tambulea, A. (author)Two realizations of finite element variational multiscale (VMS) methods for the simulation of incompressible turbulent flows are studied. The difference between the two approaches consists in the way the spaces for the large scales and the resolved small scales are chosen. The paper addresses issues of the implementation of these methods, the...conference paper 2006

Van der Vegt, J.J.W. (author), Klaij, C.M. (author), Van der Bos, F. (author), Van der Ven, H. (author)An overview is given of a space-time discontinuous Galerkin finite element method for the compressible Navier-Stokes equations. This method is well suited for problems with moving (free) boundaries which require the use of deforming elements. In addition, due to the local discretization, the space-time discontinuous Galerkin method is well...conference paper 2006

Rozza, G. (author)The reduced basis method on parametrized domains is applied to approximate blood flow through an arterial bypass. The aim is to provide (a) a sensitivity analysis for relevant geometrical quantities of interest in bypass configurations and (b) rapid and reliable prediction of integral functional outputs ( such as fluid mechanics indexes). The...conference paper 2006

Efraimsson, G. (author), Gong, J. (author), Svärd, M. (author), Nordström, J. (author)A high-order accurate multi-block Navier-Stokes code is evaluated and tested by considering the flow over a cavity in two space dimensions. Both shear layer mode and wake mode are studied. The efficiency, robustness and flexibility of the code is demonstrated.conference paper 2006

Manservisi, S. (author)Optimal boundary control problems associated with the Navier-Stokes equations coupled with the energy equation have a wide and important range of applications. Velocity, pressure and temperature describe most systems and the control through their boundary conditions is the most common in their optimal design. Despite the fact that this field has...conference paper 2006

Alzaeili, J.S.L. (author), Mazaheri, K. (author)In solution of the Euler equations in the steady state conditions, the error or residual waves are blamed for the reduction of convergence rate. These waves may be damped by adding a bulk viscosity term to the momentum equations. It was done to the Euler equations previously and in this work this method has been applied to the Navier-Stokes...conference paper 2006

Guermond, J.L. (author), Prudhomme, S. (author)The purpose of this paper is to show that the Fourier-based Nonlinear Galerkin Method (NLGM) constructs suitable weak solutions to the periodic Navier--Stokes equations in three dimensions. We re-interpret NLGM as a Large-Eddy Simulation technique (LES) and we rigorously deduce a relationship between the mesh size and the large-eddy scale.conference paper 2006

Morinishi, K. (author)This paper describes a continuum/kinetic hybrid approach for simulating the continuum to free molecule, multi-scale flows. Domain decomposition strategy is adopted for coupling the continuum and kinetic approaches. A multi-scale computational domain is decomposed into the continuum regions and the kinetic regions. Instead of the direct...conference paper 2006
