This paper presents a methodology for developing finite differences or finite volumes CFD codes on Graphical Processing Units (GPUs) through general purpose guidelines. These guidelines are applied to the implementation on a GPU of a 2D Euler equatio

Several zonal and nonzonal hybrid Reynolds-averaged Navier-Stokes/large-eddy simulation approaches have been assessed to handle a high Reynolds number supersonic base flow. The results obtained on 5 and 13.5 x 10 6 points grids are compared to the av

The side loads induced by unsymmetrical and unsteady separation of the flow taking place in the nozzle extension during launch are a very important limiting factor for the performance of a rocket engine. The onset of suchloads is not yet a fully unde

This paper presents an extension of Spalart–Allmaras model to compressible supersonic flows. The model is implemented in a three-dimensionnal structured multi domain code using a high resolution implicit upwind scheme. Details of the formulation as

Computations of steady e ows over yawing and spinning axisymmetric projectiles are largely carried out by numerical algorithms using steady methods. Of particular interest is the prediction of the Magnus force and moment. However this axisymmetric ch

This paper presents a numerical evaluation of the induced roll moment of cruciform missiles by a turbulent Navier–Stokes solver. The numerical results have been computed with a high resolution implicit upwind scheme. Comparisons with experiments pe

International audience; An overview of the Magnus effect of projectiles and missiles is presented. The first part of the paper is devoted to the description of the physical mechanisms governing the Magnus effect. For yawing and spinning projectiles,

The present paper focus on the stochastic response of a two-dimensional transonic airfoil to parametric uncertainties. Both the freestream Mach number and the angle of attack are considered as random parameters and the generalized Polynomial Chaos (g

Numerical simulation of a compressible mixing layer past an axisymmetric trailing edge is carried out for a Reynolds number based on the diameter of the trailing edge approximately equal to 2.9 × 106. The free-stream Mach number at separation is equ
