Abstract

In this paper a fluid-structure algorithm for numerical simulation of wind tunnel aeroelastic analyses is proposed. The flow equations are resolved using the artificial compressibility approach and the explicit two-step Taylor-Galerkin scheme in the context of the Finite Element [...]

Abstract

In the present work, an investigation on the Characteristic Based Split (CBS) method applied to the analysis of incompressible, transient and turbulent flows is proposed aiming at the evaluation of computational efficiency and accuracy of the present formulation considering problems [...]

Abstract

In this work we study the performance of some variational multiscale models (VMS) in the large eddy simulation (LES) of turbulent flows. We consider VMS models obtained by different subgrid [...]

Abstract

A numerical approximation for the one‐dimensional Burgers equation is proposed by means of the orthogonal subgrid scales–variational multiscale (OSGS‐VMS) method. We evaluate [...]

Abstract

A sibilant fricative /s/ is generated when the turbulent jet in the narrow channel between the tongue blade and the hard palate is deflected downwards through the space between the upper [...]
