We are interested in the numerical simulation of acoustic perturbations via the linearized Euler equations using triangle unstructured meshes in complex geometries such as the one around a complete aircraft. It is known that the classical schemes usi

A comparison between experimental and numerical data around two-dimensional de ected Hermes elevon con gurations, in wind-tunnel conditions, is discussed. The available experimental data are compared with the numerical results obtainedwith differ

Control techniques have already played an interesting role in the construction of effective methods for solving nonlinear problems in Fluid Mechanics ([1], [2]). Indeed, some limiter techniques for compressible flow simulation can be seen as projecto

We have demonstrated that Petrov-Galerkin methods can be extended to solve unsteady equations provided that consistency is preserved. This simple strategy leads to accurate methods. The simulation of the turbulent transonic flow over an ARC airfoil w

It is well known that the level of current engineering computational aerodynamic analysis for turbulent hypersonic separated flows is not satisfactory. Computations using standard two-equation turbulence models do not give sufficiently accurate predi

An implicit Finite Element code for computing viscous incompressible flows on unstructured grids is described. The foundation of the code is a SUPG stabilization applied for both velocity and pressure. A backward Euler time discretization for which t

We discuss in this paper the numerical solution of boundary value problems for partial differential equations by methods relying on compactly supported wavelet approximations. After defining compactly supported wavelets and stating their main propert

In this article we briefly discuss a fictitious domain method for the numerical solution of the Navier-Stokes equations modelling incompressible viscous flow. The methodology described here takes a systematic advantage of time discretization by opera
